From ef774ee93cb561d072137f2a11c2d347bedf6342 Mon Sep 17 00:00:00 2001 From: Shane Kearns Date: Fri, 2 Sep 2011 18:40:45 +0100 Subject: Restore Qt4.7 behaviour of QFileInfo::absolute(File)Path Many applications relied on the undefined behaviour that the filesystem engines returned clean paths (despite the documentation stating that they may not), and consequently suffered regressions with Qt 4.8. Unix paths are once again cleaned if necessary. Windows/Symbian paths were already cleaned, but now use the utility function to check if a path is dirty, to avoid duplicated code.
