textmodes/flyspell.el: Delay for otherchars as for normal word components.

(flyspell-check-pre-word-p,
 flyspell-check-word-p,
 flyspell-debug-signal-word-checked):

Use for otherchars the same delay used for other word components, so word
is not inmediately checked unless we are in a char that is neither a normal
word component nor an otherchar.
