[PATCH] shell-forward-word error with quoted comsub

[Grisha Levit]

Calling shell-forward-word in front of an incomplete quoted command
substitution causes a parser error to be printed, which is followed
by an incomplete redisplay:

    $ "$(" ^A\e^F
    bash: command substitution: line 2: unexpected EOF while looking
    for matching `"'

even when the word is single-quoted:

    $ '$(' ^A\e^F
    bash: command substitution: line 3: unexpected EOF while looking
    for matching `''

There might be a more general fix but this patch seems to work.
