test-lib: prevent '--stress-jobs=X' from being ignored
'./t1234-foo.sh --stress-jobs=X ...' is supposed to run that test
script in X parallel jobs, but the number of jobs specified on the
command line is entirely ignored if other '--stress'-related options
follow. I.e. both './t1234-foo.sh --stress-jobs=X --stress-limit=Y'
and './t1234-foo.sh --stress-jobs=X --stress' fall back to using twice
the number of CPUs parallel jobs instead.
The former has been broken since commit de69e6f6c9 (tests: let
--stress-limit=<N> imply --stress, 2019-03-03) [1], which started to
unconditionally overwrite the $stress variable holding the specified
number of jobs in its effort to imply '--stress'. The latter has been
broken since f545737144 (tests: introduce --stress-jobs=<N>,
2019-03-03), because it didn't consider that handling '--stress' will
overwrite that variable as well.
We could fix this by being more careful about (over)writing that
$stress variable and checking first whether it has already been set.
But I think it's cleaner to use a dedicated variable to hold the
number of specified parallel jobs, so let's do that instead.
[1] In de69e6f6c9 there was no '--stress-jobs=X' option yet, the
number of parallel jobs had to be specified via '--stress=X', so,
strictly speaking, de69e6f6c9 broke './t1234-foo.sh --stress=X
--stress-limit=Y'.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-<commandname>.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
