I'm not sure whether this is the right patch.  Currently, you should
add `-ma4 -P-pa4' to the command line while calling groff to get
proper defaults for page length and line length.  Providing a special
register PL for the page length probably makes the user think that
changing the PL register has an influence on the physical page length
also.  Normally, you won't change the page length at all within a
document (except for suppressing trailing empty lines in TTY output).

Instead, I suggest to add a note to the docs which explain why there
isn't a `PL' register :-)
