Subject: git-init: autodetect core.symlinks
X-Git-Tag: v1.5.3~19
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=75d244990364e322e87e2549846b17252f440627;p=git.git

git-init: autodetect core.symlinks

We already autodetect if filemode is reliable on the filesystem
to deal with VFAT and friends.  Do the same for symbolic link
support.
