Attached patch adds the following line about the form id to the Forms
API quickstart guide.


"
Because the form ID can be used in functions, you have to make sure it
is a valid PHP label. A valid form ID starts with a letter or
underscore, followed by any number of letters, numbers, or underscores.


"
Though form IDs do not have to be valid PHP labels per se (see eg CCK),
invalid form IDs break a good deal of FAPI.
