*sigh*  I say these things, I tinker with documentation for the options
etc, but do I remember to write documentation for the new module?

See attached, relative to the source tree as patched by the previous

+Interface to the POSIX regex library.
+cindex(regular expressions, REGEX)
+The tt(zsh/regex) module makes available the following test condition:
+item(expr tt(-regex-match) regex)(
+Matches a string against a POSIX extended regular expression.
+The matched portion of the string will normally be placed in the tt($MATCH)
+variable.  If there are any capturing parentheses within the regex, then
+the tt($match) array variable will contain those.
+For example,
+[[ alphabetical -regex-match ^a([^a]+)a([^a]+)a ]] && print -l $MATCH X $match
+If tt(REGMATCH_PCRE) is not set, then the tt(=~) operator will automatically
+load this module as needed and will invoke the tt(-regex-match) operator.
+If tt(BASH_REMATCH) is set, then tt($BASH_REMATCH) will be set instead of
+tt($MATCH) and tt($match).
