[m-dev.] for review: enhancements to mtags script

G'day.

I did check this before I mentioned this.  All of the instances of
this this pattern were at the bottom of loops or within the body of
an if, which means that if $_ was used implicitly, the code deserves
to break. :-)

I objected in this case.  Not only did it save a line, it's a lot
more readable.

I did notice this too.  Some of the long chains of expressions such as:

	next unless (
		something ||
		$body =~ /--->/ ||
		$body =~ /=/ ||
		$body =~ /::/
	);

would look a bit neater using $_ instead.

Neither brevity nor streamlining are really huge concerns for mtags.
Now maybe if we'd written mdemangle in Perl...
