    The EVE_MATCH_DELIMITORS I posted early last week works correctly in
matching the parentheses (you didn't say WHAT you thought the unexpected
behaviour to be) for the _second_ case (perhaps you ought to _try_ the
procedures rather than just guessing :-), but the first case is tougher
because there's an "extra" copy of the delimiter you're trying to match
within a quoted string.

    I believe you're be asking the MATCH procedure to know a given
language's syntax for "quoting" a string, and to ignore  delimiters
embedded within those strings.  I can think of ways to do that, but I can
imagine more cases of it making the _wrong_ choice rather than the right
one... You basically have to search the WHOLE buffer to see if you're
within a (language-specific-syntax) quoted string.  I wouldn't want to
attempt that, I'd rather let the compiler catch _those_ cases...  "Operator
intervention" in the relatively infrequent cases, like your first example,
shouldn't be to ask :-)
