- the switch is done by the Subversion library. TSVN doesn't do the
switch itself.
- So TSVN doesn't know which files/folders are really affected by the switch
- Even if TSVN knew (we could just guess), the check wouldn't really be
accurate: a file/folder could be locked during the check but not be
locked shortly afterwards, or it could *not* be locked, but then it
could be in use by another program when the actual switch happens.
