Deprecated since 6.02
86.Extended $hfind(name/N, text, N, M) to handle wildcard/regex
matches. Where M is:
n - normal text comparison (default if M isn't specified)
w - text is wildcard text
W - hash table item/data is wildcard text
r - text is regular expression
R - hash table item/data is regular expression
Note: $hmatch() and $hregex() are still supported for now but
are no longer listed in the help file.
