Subject: Bugfix: Default RSS feed failed feed validation at http://www.feedvalidator.org/... 
X-Git-Tag: debian/2.1.2-2~39
X-Git-Url: https://git.deb.at/w?a=commitdiff_plain;h=4ca079445f95088dac8bdc7506aa04696513fb12;p=pkg%2Fblosxom.git

Bugfix: Default RSS feed failed feed validation at http://www.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.
