(lm-get-header-re): Allow spaces between the header and the colon.

(lm-header-prefix): Cleanup the regexp.
(lm-header): Allow $ in non-RCS headers.
(lm-header-multiline): Put the strings back into order.
Stop at an empty line.  Don't require two space chars if the
line is clearly not another header line.
