style.9: update C99 commentary

Make style.9 read as a current statement of C99 preferences, rather than a
description of ongoing changes to our preferred style.  Alsu use the short
form "ISO C99" on the 2nd and later instances rather than repeating the
unwieldy `ISO/IEC 9899:1999 ("ISO C99")` each time.
