and that's it. They use the scm_tc7_ssymbol tag (S bit clear).
Msymbols are symbols with extra slots. These slots hold a property
- list and a function value (for Emacs Lisp compatibility), a hash
- code, and a flag to indicate whether their name contains multibyte
- characters. They use the scm_tc7_msymbol tag.

We'd like SCM_CHARS to work on msymbols just as it does on
ssymbols, so we'll have it point to the symbol's name as usual, and
