If you want {...} to pick up a string, then set up a "braced string"
recognition pattern, probably best with start and end REs. eg start: \{
end: \} matching error: \n say. A # between the braces then becomes a
character in the string. Make sure you move the pattern to a position just
after the Single Quote String pattern. But then you'll have two other
problems: nested braces (are such things valid in TCL string?) or highlighting
within a brace-string, and braces when used for other reasons (are there any?)
where you'll have to give REs that provide a bit of context. It can get
tricky!
