Subject: Add tests for documented features of "git reset".
X-Git-Tag: v1.5.4-rc0~434^2~4
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=359048d6ec296757266887a8ced5a927b97b94c1;p=git.git

Add tests for documented features of "git reset".

This adds the new file t/t7102-reset.sh following the text
and examples in "Documentation/git-reset.txt" in order to
check the behaviour of the upcoming "builtin-reset.c",
and be able to compare it with the original "git-reset.sh".
