[mercury-users] Proposed change to char literal syntax

We have not worked out the details.  One option is to
- require character literals to appear in single quotes
- make quoted symbols lose any "fixity" (so '+', say, will not be
  interpreted as an infix symbol).

But we already use single quotes to delimit odd function symbols (e.g.,
ones starting with capital letters).  It's not clear precisely what the
solution is, but it won't be syntactically heavy and it will require
users to change some of their programs.
