Wouldn't it have been better to put these in the $match array (or into
some other named array) the way that backrefs in glob patterns do?

$1 etc. in Perl are not positional parameters -- you don't lose access
to @ARGV when you do a pattern match.  I think clobbering the positionals
is more harmful than helpful; if you want to be able to reference $1 etc.
you can always do

	pcre_match ...
	set - "$match[@]"	# or whatever it is named

For comlete generality, pcre_match could take the name of the array to set
as an argument; then the above could be accomplished with

	pcre_match -a argv ...

(where I've chosen -A somewhat arbitrarily, and another character might be
better).
