"svn merge" scans the whole wc and deletes svn:mergeinfo properties

I wanted to undo a changeset (24504) that modified only two files. So
I did a "svn merge -c-24504 .", and to my surprise, it took more than
2 minutes, scanning the whole working copy. And a "svn diff" showed
that many svn:mergeinfo properties are deleted on other files (note:
these properties are empty). Is this normal? Have I done anything
wrong? This is annoying because I suppose that unrelated files would
get a log message for that! (I didn't try the commit.)
