```
In some cases, the svn author names might contain leading or trailing
whitespaces, leading to messages such as:

  Author: user1
   not defined in authors.txt

(the trailing newline leads to the line break). The user "user1" is
defined in authors.txt though, e.g.

  user1 = User <user1@example.com>

Fix this by trimming the author name retreived from svn before using it
in check_author.

This fix seems incomplete. What happens if $author is undefined?
(There is a check for $author defined'ness just below the new code you
add.)

Right, thanks for noting. The whitespace trimming should be moved below
the defined'ness check. I'll send an updated patch.
