Hi,
Terribly sorry for the long delay, I've been away on vacation till
now.

This is a general problem, does not apply only to Mercury. The
problem is caused by `prolog-char-quote-workaround' being set
(non-nil, default). When this variable is set the character 0 is
defined as a quote characrer in order to handle pseudo-correctly the
construct 0'a and the such. The side effect is that in the construct
0) the parenthesis is in effect quoted.
I know about this problem annd I have no idea how to fix it (help is
appreciated by the way). I quote the documentation of the variable:
"If non-nil, declare 0 as a quote character so that 0'<char> does not
break syntax highlighting. This is really kludgy but I have not found
any better way of handling it."
In all, the fix of this bug is to set `prolog-char-quote-workaround'
(customizable variable in the group "Prolog Other") to nil. This will
break the character escape sequence but I have no idea how to handle
both.
If you have a better idea I would again be extatic to hear it.
Cheers,
Stefan
