1. How do I construct a regular expression that will search for any
character that isn't part of a symbol? I know that "\\sw\\|\\s_" will search
for anything that is a word constituent or a non-word symbol constituent, but
how do I negate this? I need something like "[^\\sw\\s_]", but the "[^...]"
construct only takes characters, not character descriptions.
2. a. Is there any way to negate regular expressions in general?
b. Or OR or AND them? Something line (REGEXP-OR "foo" "bar") might be
useful instead of "foo\\|bar", if only for readability.
c. Is there an analog of "\\|" for AND?
I couldn't find anything in (emacs)Regexp in the Info browser.
