From: Junio C Hamano Date: Mon, 4 Feb 2008 07:59:17 +0000 (-0800) Subject: builtin-mv: minimum fix to avoid losing files X-Git-Tag: v1.5.5-rc0~184^2 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=744dacd3f5045240a304e687f3ef7135398e7865;p=git.git builtin-mv: minimum fix to avoid losing files An incorrect command "git mv subdir /outer/space" threw the subdirectory to outside of the repository and then noticed that /outer/space/subdir/ would be outside of the repository. The error checking is backwards. This fixes the issue by being careful about use of the return value of get_pathspec(). Since the implementation already has handcrafted loop to munge each path on the command line, we use prefix_path() instead.
