Subject: 23.0.60; Shell-script coloring bug

In shell-script mode (at least for Shell-script[sh]), in the following line:

for i do

the token “do” is not colored as a keyword, which it should be. From
the relevant POSIX documentation:

http://www.opengroup.org/onlinepubs/000095399/utilities/xcu_chap02.html#tag_02

The format for the for loop is as follows:

    for name [ in [word ... ]]do
        compound-list


    done

Note that there is no explicit mention of semi-colons (this appears to
be the issue, as if the line is changed to

for i; do

then it is colored correctly, although in fact this syntax is NOT
permitted by POSIX, although bash accepts it.) A semi-colon is only
needed (and indeed, rqeuired) when an “in” clause is used, as the
“word” list mentioned above must end in a semicolon.

Hence, two things seem to need fixing:

1. In Shell-script[sh,bash] modes, “for name do” should color “do” as
   a keyword.

2. In Shell-script[sh], “for name; do” should *not* color “do” as a
   keyword.
