Sharp (#) in commands...

[Paul M . Lambert]

We've got a user that wants access to a CD mounted in a drive.  The
CD has a filesystem on it that includes a directory containing a
sharp (the '#' character) in the directory name.

We want to restrict a few commands to that specific directory.  The
parse.lex lexer has a bug regarding the '#' sign, according to the
one and only bug in the bugzilla database.

We _really_ need this to work.  For now, we're going to make a symlink
elsewhere on the hard drive to the directory on the CD.  But it makes
us look bad to provide this to the customer.

It'd be nice for the # symbol to be escapable just like any other
'special' character.
