Following up from comment 7 in bug 44336 <https://bugs.webkit.org/show_bug.cgi?id=44336#c7>, we should implement support for recognizing the svn:mergeinfo property so that patches that contain such information can be applied.
Created attachment 66594 [details] Patch with unit tests Adds support for recognizing the svn:mergeinfo property and ignore it. Because svn:mergeinfo is metadata that is used only by SVN and tends to be error-prone and/or nuisance (see remark (*)), we will ignore it for now. That is, when applying a patch that contains svn:mergeinfo info the changes to the svn:mergeinfo property will not be applied. (*) See "Parting Thoughts" of <http://www.collab.net/community/subversion/articles/merge-info.html>.
I should add that I don't really use svn merge and hence could be biased on its benefit. I am open to suggestions on whether we should keep this information.
Comment on attachment 66594 [details] Patch with unit tests Looks sane.
