Subject: 23.2; man command can no longer accept -k, spaces
Date: Sun, 30 May 2010 23:52:54 -0700

M-xman will no longer allow '-k pattern' or '1 cat', even though the
help documentation claims this should work. This appears to be
due to the completion functionality, which has no documentation
way to disable it

  M-x man RET 1 SPC cat RET

works for me.  Admittedly, for -k you have to work a little harder, but:

  M-x man RET -k C-q SPC haskell RET

works.  I've just installed the patch below which makes

  M-x man RET -k SPC haskell RET

work as well.

The completion code only enters into the picture if you actively
call it.  Sadly, SPC is bound to a command that calls completion, so you
sometimes need C-q SPC to insert a space when you need to override the
completion code.
