Subject: file_exists(): dangling symlinks do exist
X-Git-Tag: v1.5.4-rc0~78^2~17
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=a50f9fc5feb0a8b8afe51e75ae7c7a87446113e3;p=git.git

file_exists(): dangling symlinks do exist

This function is used to see if a path given by the user does exist
on the filesystem.  A symbolic link that does not point anywhere does
exist but running stat() on it would yield an error, and it incorrectly
said it does not exist.
