Thanks. Will get our users to modify their code. Was not sure what the
decision would be, and I shouldn't have been so terse in the ticket.
But 2 things that you might want to consider.

1. Older versions 4.5, worked differently:
      $ ssh -V
      OpenSSH_4.5p1, OpenSSL 0.9.8d 28 Sep 2006
      $ sftp `hostname`:/tmp/a#a
      Fetching /tmp/a#a to a#a
   But newer versions:
      $ ssh -V
      OpenSSH_5.8p1, OpenSSL 0.9.8a 11 Oct 2005
      $ sftp `hostname`:/tmp/b#b
      File "/tmp/b" not found.

2. I was also under the impression that the '#' started a comment, but
after seeing how from the shell we had to quote the '#', it doesn't
look like all of the shell's parsers that I tested worked that way. It
looks like the '#' only starts a comment at the beginning of a token:
      $ touch #a
      touch: missing file operand
      Try `touch --help' for more information.
      $ touch a#a
      $ ls a#a
      a#a


Thanks again for any additional thought on this.
