I think you are missing the point. R:foo is relative to the current
working directory. The current working directory is set using a windows
API. Tortoise runs in the context of Windows Explorer. Windows explorer
might use this API, Tortoise might use this API, and anything else that
runs in the same context (other plug-ins, etc) may use this API. The
last call wins.

I am not arguing that there isn't a bug here. I am just pointing out
that using a relative directory in this context might result in
unpredictable results. You are more than welcome to leave of the '\' but
don't be surprised if you get random or incorrect results.

This is helpful information. Before I replied to you I tried exporting a
small directory and saw the export dialog for only a brief moment. Since
I am using a 5 year old computer it's quite possible that it might be
missed on a faster computer.

I am pretty sure that the current working directory for each drive
letter is tracked per process. Type 'cd r:\foo' open a new command
prompt and then type r:. You'll notice each process has a different
value for pwd.

Now try this. Open up the run dialog and enter this command 'cmd /K
"r:"'. Your command prompt will probably look something like this
'R:\>'. Now type 'C:'. Does your prompt look like 'C:\>'? My guess is
that it does not.

Explorer is much more complicated. Maybe it never sets the working
directory so it's always the default. R:foo works great but then you
install Joe's nifty Explorer plug-in that cures world hunger. For some
reason Joe's plug-in sets that working director to 'r:\bar' and now
'r:foo' turns into 'r:\bar\foo'.

I did notice that the version of Tortoise SVN (TortoiseSVN 1.6.10, Build
19898) that I am using tells me that
'c:foo' is an invalid directory. I get the same message whether foo
exists or not. This seems reasonable to me since c:foo is kind of
ambiguous.

It's possible that the 1.7 version also rejects that path later on but
doesn't produce and error message.
