fix #H7702 - named fruit warning: singular of null

Browse Source 
Some code added for 3.6.1 tries to find the longest matching prefix
when comparing a user-supplied with previously set up fruit names.
It does so by temporarily replacing space with NUL then passing that
to makesingular().  After already having named a fruit (resulting in
something to try to compare with), attempting to assign a name
beginning with two or more spaces would yield an impossible "singular
of null?" warning.

After the warning, the name minus its leading spaces got successfully
assigned.  I'm not sure why a single leading space didn't trigger it
too, nor where the leading (and trailing, if any) spaces are going
away when the name is assigned.

Fix by removing all leading and trailing spaces from a new fruit name,
and combine consecutive internal spaces to one, before any other
manipulations.  (This can result in names that used to work as-is now
being simplified a bit--when consecutive internal spaces have been
given--but that shouldn't be a problem.)

Also, don't complain about "missing parameter for 'fruit:'" if user
hits <return> when prompted for fruit name by 'O'.  An empty fruit
name at that stage is just a no-op.
