git-svn: convert SVK merge tickets to extra parents
SVK is a simple case to start with, as its idea of merge parents
matches git's one. When a svk:merge ticket is encountered, check each
of the listed merged revisions to see if they are in the history of
this commit; if not, then we have encountered a merge - record it.
