As I said originally, I wasn't sure whether this ever worked.  Clearly
it never did (I just reverted to 0.6.16_svn to make sure), so sorry
for all the noise! (interesting behaviour on Ville's machine, though)

Having the quote close automatically is handy.  Would it be
counter-intuitive if

'/home/'<TAB>

completed to

'/home/stefan' ?

It's a minor annoyance (I've never seen anyone else complain), so
really not that important; but if you do get a chance to take a look,
I would appreciate it.

Thanks
