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.  :-)
