Minor tweaks in the description of %g:
1. Clarify that %G uses %F, not %f; noticed by millert@.
2. Mention that %g originally meant "general notation", see:
https://minnie.tuhs.org/cgi-bin/utree.pl?file=V7/usr/src/libc/stdio/doprnt.s
Triggered by a somewhat different patch from Ian <ropers at gmail dot com>.
Feedback and OK millert@ and jmc@.
