Subject: git-submodule.sh: setup uninitialized variables
X-Git-Tag: v2.27.0-rc0~93^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=65d100c4ddbe83953870be2e08566086e4b1cd3c;p=thirdparty%2Fgit.git

git-submodule.sh: setup uninitialized variables

We have an environment variable `jobs=16` defined in our CI system, and
this environment makes our build job failed with the following message:

    error: pathspec '16' did not match any file(s) known to git

The pathspec '16' for Git command is from the environment variable
"jobs".

This is because "git-submodule" command is implemented in shell script,
and environment variables may change its behavior.  Set values for
uninitialized variables, such as "jobs" and "recommend_shallow" will
fix this issue.
