Subject: [PATCH 2/5] gitweb: Use "return" instead of "return undef" for some subs

From: Jakub Narebski <[email-masked]>
Date: Tue, 26 Sep 2006 01:56:17 +0200

Use "return" instead of "return undef" when subroutine can return, or
always return, non-scalar (list) value.

Other places are left as is.
