Subject: Only mangle $blosxom::title and body if defined.
X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;h=d6c63378cfe2403fae3ff11eea5d5964d3db46c5;p=matthijs%2Fupstream%2Fblosxom-plugins.git

Only mangle $blosxom::title and body if defined.

This fixes a warning when the do_interpolate route is called to
interpolate non-story templates.
