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.

BTW, pushed to `master`, thank you.
