Why can I not construct a regex of the form: "|abc" (throws exception based
on REG_EMPTY) for use with regex_match, if I want to match either "abc" or
the empty string "". I understand thatn in a regex_search the empty string
would always match (per Perl like semantics), and abc would never be
considered. But, I want to use this with regex_match, where the empty string
would have to match the entire string being searched. Work arounds such as
"(?:)|abc" and "^$|abc" seem to get around this deficiency, but I am
wondering why it is there in the first place.
