options.c formatting; glob as named fruit

This started out removing one tab and I got carried away.  It moves
some labels to column 2, removes some parentheses where sizeof is
used on strings rather than types, adds or revises several comments,
replaces a couple of 'while' loops which can be simplified as 'for'
loops, and updates named fruit handling.

"glob of black pudding" became "candied glob of black pudding" if used
as a fruit name, but "small glob of black pudding" was used as-is and
became indistinguishable from an actual small glob.  Unless you had
more than one; then you could try to check whether they merged into a
stack or coalesced into a bigger glob (but if neither of those changes
happened, you still couldn't tell which was the glob and which was the
named fruit).
