Subject: Bugfix: Default RSS feed failed feed validation at http://www.feedvalidator.org/... 
X-Git-Tag: v2_1_0~9
X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;h=4ca079445f95088dac8bdc7506aa04696513fb12;p=matthijs%2Fupstream%2Fblosxom.git

Bugfix: Default RSS feed failed feed validation at feedvalidator.org/ if there was a blank inside a file name since blanks (and other characters) need to be escaped inside an URL. Most browsers do this, but not all.
