Why? Those are temporary files. And we must create temporary files for
that. Also we can't remove those files automatically, because they're
used by the diff-viewer. And of course, you can diff the same files
multiple times with different revisions, so the filenames *must* be unique.

If I do the exact steps you mention above, TortoiseMerge nicely shows
the filenames and the revision numbers they're from, not the temp file
names. I don't know which diff tool you use, but if it can't handle the
name params TSVN can pass to them, then it's your diff tools fault, not

Now you diff 'move_long.c' from revision 1569 with revision 1900, and
the diff would fail because '1569.move_long.c' already exists.

The ".i" would be the file extension of the file. We do that because
some diff viewers need the real file extension to work properly.

[snip signature and *8* quotes]
What the hell is that for? I don't mind signatures or quotes at the end
of the mails, as long as they're small in size (common understanding is
that they must not exceed four lines). But you really just broke every
record: 8 quotes!
