But the user has to have done something in order to change the keywords
or the EOL characteristics, right? Don't we already know that
svn:keywords or svn:eol has been changed and force the file itself to be
considered "changed" for purposes of status?

False positives are merely a waste of a little CPU (since we'll go
through the motions and then do nothing), whereas false negatives may
cause loss of information (i.e. I run `svn st` and seeing none, blow
away my WC, not realizing that there _are_ changed files). I vote for a
chance of false positives if that [significantly] reduces the chance of
false negatives.

My 2 cents...
