Subject: [PATCH] git-mv: add more path normalization
X-Git-Tag: v1.4.2.1~4
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=d78b0f3d6aa04510dd0c22c3853d3954c5f5b531;p=git.git

[PATCH] git-mv: add more path normalization

We already use the normalization from get_pathspec(), but now we also
remove a trailing slash. So,

	git mv some_path/ into_some_path/

works now.

Also, move the "can not move directory into itself" test before the
subdirectory expansion.
