It would notice that the svn book keeping was already up-to-date
when it went to update it.
This of course probably requires several currently non-existing
apis in subversion: an api to 'move' the file when it has already
been moved in the file system, and an api to find out if the
file has been moved in the in subversion.
In addition, it might require that TSVN working copies that you
wanted to operate in this fashion be registered so that TSVN can
watch them and not perform expensive analysis on all file system
operations to see that they shouldn't be translated to svn
operations. This might not be necessary if we could eliminate
operations outside of a working copy quickly enough.
I'm not really even sure I'm advocating such a feature ... but
it would be slick if it could be made to work.
Thanks,
Joseph
