Leaving unversioned local files alone in a directory is not the problem.
I've personally ran into scenarios where the local directory contained
unversioned local files that obstruct a file that will be added by a
switch/update/merge/what-have-you. If the local file's content matches
the content in the repository, then I think it is safe to simply replace
the unversioned local file with the versioned file from the repository.
Often, the content has not been the same. It all depends on a lot of
factors such as how it became unversioned, what has happened to the file
while it was unversioned, etc. Replacing the content of the local file
with the content in the repository looses local data. Merging the
unversioned content and the versioned content usually result in poor
merges (in the best case scenario) because there is no base revision to
use in the 3-way merge. I've seen merges like this get committed
accidentally and cause havoc. Of course, using the unversioned local
content instead of merging the content from the repository could
accidentally replace the entire contents of the file and this can
accidentally get committed as well. Subversion needs the user's help to
figure out what to do and marks these conflicts as tree conflicts.
