Subject: [PATCH] Test GIT environment use.
X-Git-Tag: v0.99~573
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=947adb2739845df3421c0f9647a68acad70c2614;p=git.git

[PATCH] Test GIT environment use.

This test makes sure that use of deprecated environment variables still
works, using both new and old names makes new one take
precedence, and GIT_DIR and GIT_ALTERNATE_OBJECT_DIRECTORIES mechanisms
work.
