I didn't expect it, but I'm completely unsurprised. svn:keywords have
to rendered, and switching an upstream repository, branch, tag, etc.,
etc. can all change the WebURL, Author, Date, and other keywords. So
I'd be completely unsurprised if all files with svn:keywords get
reparsed and touched, even if no change results in the end.

Tis is one of the fragilities of keywords in all source control
systems. innocuous changes with no change in performance lead to
modifications of source files, even such innocuous changes as comment
lines.
