Problem: A SAL rule longer than MAXWLEN is silently truncated to an
empty lead. set_sal_first() then reorders the sl_sal entries
by their index byte and can move the terminating sentinel out
of the last slot, so spell_soundfold_wsal() reads past the end
of the array, e.g. when soundfold() or spellsuggest() is used
(Erick Alex).
Solution: Bound the sound-folding loops against sl_sal.ga_len.

Problem: When z= fails due to no word being found, 'spelllang' being
unset or a multiline visual selection, 'nospell' is not
restored.
Solution: Jump to where the user configured value of 'spell' is restored
instead of returning early (Luuk van Baal).

Problem: Too many delete() calls in tests.
Solution: Use deferred delete where possible.
