Subject: setup: translate symlinks in filename when using absolute paths
X-Git-Tag: ko-next~29^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=18e051a3981f38db08521bb61ccf7e4571335353;p=git.git

setup: translate symlinks in filename when using absolute paths

otherwise, comparison to validate against work tree will fail when
the path includes a symlink and the name passed is not canonical.
