Subject: Space resolution bugfix: Space specifiers didn't collapse when there was not break... 
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=f63d84f4e4ec41941b464ec07dc964b51cdb1f24;p=xmlgraphics-fop.git

Space resolution bugfix: Space specifiers didn't collapse when there was not break in the sequence.
Test case for space resolution in side regions. This test case showed me the above bug.

git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/branches/Temp_SpaceResolution@326545 13f79535-47bb-0310-9956-ffa450edef68
