Subject: [PATCH 2/3] Support symlinks in git-ls-files --others.
X-Git-Tag: v0.99~587
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=a15c1c60db9abb981754b1ba3b899f49949ae8b7;p=git.git

[PATCH 2/3] Support symlinks in git-ls-files --others.

It is kind of surprising that this was missed in the last round,
but the work tree scanner in git-ls-files was still deliberately
ignoring symlinks.  This patch fixes it, so that --others will
correctly report unregistered symlinks.
