Subject: trust-executable-bit: fix breakage for symlinks
X-Git-Tag: v1.4.4.1~1

trust-executable-bit: fix breakage for symlinks

An earlier commit f28b34a broke symlinks when trust-executable-bit
is not set because it incorrectly assumed that everything was a
regular file.

Reported by Juergen Ruehle.
