Allow return code of '1' from 'svn propget'
Review Request #6325 — Created Sept. 15, 2014 and submitted — Latest diff uploaded
SVN 1.9 has apparently decided to break the "API" of the 'svn propget' command
by making a return value of '1' indicate success. This change adds that return
code to the allowed errors for the command.
I don't have SVN 1.9, but I made sure that propget still worked correctly on
1.7.x.
