* You might think that this could be incorporated into regcomp.c, and
* that would be a reasonable idea... except that this is a generic
* function (with a generic name), applicable to all compiled REs
* regardless of the size of their characters, whereas the stuff in
* regcomp.c gets compiled once per character size.
* pg_regfree - free an RE (generic function, punts to RE-specific function)
* Ignoring invocation with NULL is a convenience.
