the next part checks whether the file is below 512k,
so there's no point checking if it's below 2, because
the lowest a file size can be is zero, and expr will
produce a result of -1 if decrementing from zero.

merge it with git_prep, since it's only a small
function and only called from there. the merged
code still makes sense and its purpose is still
quite clear on casual reading.

the "u" argument can actually be any thing. git_prep
handles git submodules only for single-tree projects,
under any candition, or on multi-tree projects if
the number of arguments to git_prep is above four.
"u" is the 5th argument, meant to enable submodule
downloads. it really doesn't matter what this string
says, so let's just make it as clear as possible.

the combination of x_ with the "e" function enables
for much simpler file-check error handling, which is
a unique innovation of lbmk as it pertains to sh.

the cbfs function will call cbfstool, which will perform
the same check, and the same error condition would cause
the same exit behaviour in lbmk. the error message would
also provide output that is just as useful for debugging.

There was no error handling, *at all*, on the actual tar
command, due to the lack of set -o pipefail, which we cannot
rely on in sh.
The x_ wrapper can be used in this case, as a mitigation.

it wouldn't exit with error status anyway, since i'm
setting +e here, but if that accidentally changed in
the future, i still wouldn't want this to exit.
the bruteforce me extraction naturally throws a lot of
errors, hence +e, because of how the extraction works,
but the result is checked at the end of the process,
to compensate. hence +e, because otherwise this brute
force extraction would never work.
therefore, this is an extremely theoretical bug fix, the
most quintessential of preemptive bug fixes, to the point
that it is actually rather pedantic.
The ":" in "|| :" will likely *never* be executed, but it
handles the theoretical case where the subshell exits with
non-zero status and +e is set; subshells aren't meant to
behave this way anyway, but who knows what cursed sh
implementation the user is on?

We can't do set -o pipefail in POSIX sh, which we're using,
but the build system has x_ which wraps around a command
and executes it, exiting with non-zero status if it does.
This fact enables lbmk to have functionality that is actually
superior to pipefail, since you can more easily control
specifically which parts error.
For example:
foo | bar | foo2 | bar2 | $err "error"
ERROR exits with non-zero status, but foo2, bar and foo
would not exit on error, only bar2 would. In *bash*, which
we avoid, set -o pipefail would make all of them exit on
error, but what if you wanted "bar" to not exit?
With lbmk, you could do, in the above example, and with the
above question asked ("what if you wanted bar not to exit"):
x_ foo | bar | x_ foo2 | bar2 > file | $err "error"
of course, you could also do, if not outputting to "file":
x_ foo | bar | x_ foo2 | x_ bar2
NOTE: in lbmk, $err is a variable containing the name of
a function that does something (whatever you want) and
then exits with non-zero status.
This entire explanation is beyond the scope of simply
providing (and explaining) this fix, but I also wanted to
use this commit as an example of the power of lbmk with
regards to POSIX shell scripting.

in these if clauses, what follows afterward is exactly
the same: set xchanged and return.
Therefore, these lines are redundant and they can be
removed.

This change finally ensures that no insertions will be
attempted, on the basis that readkconfig failed; this
covers the instance whereby vcfg was set, but no scanned
items were indicated e.g. Intel ME files not specified.

This should speed up automated tests. Otherwise, it goes
through all the extra checks that aren't needed, for each
individual type of vendor file, and also errors out when
handling pico serprog images; during automated testing,
on the bin directory, you might try on every tarball, one
of which is the pico tarball and this patch makes lbmk skip
that one too.
In general, we must not perform unnecessary tasks. Doing so
may even cause other bugs that we couldn't easily detect.

This reverts commit 3bfdecdc75bbc77f795736ac282f858f2eb7ab94.
The commit that this reverses, caused sch5545 ec firmware
downloads to fail, due to globbing.

x_ cannot be used, where output is redirectod to a file;
only the conventional piping can be used.
same as the last change. this and the other fix were caught
during testing.

I was using a complicated method of knowing whether
the current instance was parent or a child, to know
whether the lock file and TMPDIR needed to be purged.
It was quite error-prone too. Instead, I'm now handling
it directly from within the if statement that previously
initialised xbmk_parent=y, forking ./mk from there.
The forked instance would not trigger that if clause
again, since then TMPDIR is created, thus avoiding
recursion.
This is an improvement because it doesn't rely on how
the parent handles exit statuses, and it ensures that
the lock/tmp files are never accidentally deleted.
Even if a given program/script that lbmk runs would
export TMPDIR, it doesn't matter because lbmk doesn't,
so it would be unaffected.

script/ no longer exists. this means that the
only executable script in lbmk is now mk.
script/trees was never called directly; instead,
we used ./update trees in the past, then just ./mk.
this is part of a larger audit to simplify lbmk,
in preparation for the next Libreboot release.
