Subject: Use the output of 'svn status' instead of doing a custom and error-prone .svn-parsing... 
X-Git-Url: https://cloud.milkyroute.net/gitweb/dolphin.git/commitdiff_plain/47615514f8617c64852ca2c4398dc6ba151317b5

Use the output of 'svn status' instead of doing a custom and error-prone .svn-parsing. BTW: this commit is the first done within Dolphin itself :-)
