In hindsight, I wish we had reserved all of the "fun" characters
like !@#$%^&*():;~'"\ and prevented them from ever appearing in a
ref name.
Instead only what check_ref_format() in refs.c ll.694 tells is
is reserved:
671 /*
672 * Make sure "ref" is something reasonable to have under ".git/refs/";
673 * We do not like it if:
674 *
675 * - any path component of it begins with ".", or
676 * - it has double dots "..", or
677 * - it has ASCII control character, "~", "^", ":" or SP, anywhere, or
678 * - it ends with a "/".
679 */
Heh. At least : and SP are reserved.
Use BEL for your %helloworld hack. It'll be fun to type. :-)
