451665cb2a 'main': Don't highlight at the $PS3 prompt.
The input to the $PS3 prompt is not commands, so the 'main' highlighter is
not applicable to it.

Fixes zsh-users/zsh-syntax-highlighting#268.

Therefore, under zsh older than 5.1, quoting is required.

This manifested as random «builtin=''» in emitted to the terminal, and
commands (such as 'echo') highlighted as errors (in red).

is no test because the tests only check highlighting of BUFFER, and 'bar"'
is already highlighted correctly.

784a5dc35b protect alias expansion from interpreting aliases as options
If one defines aliases like `++` the alias builtin tries to interprete these
as options so they have to be protected like this

    alias -- ++=true

The same goes for a call to `alias` in order to expand the alias again.

441f1a8aad highlight array assignments of the form x[y]=...
This code is more lenient than bash.  Examples:

    $ x[y[]=
    zsh: no matches found: x[y[]=
    $ x[][]=
    zsh: no matches found: x[][]=

The proper solution is to look inside the [...] and make sure that all
unescaped/unquoted square brackes are matched, but that is a heck of
a lot more complicated than this simple 8-character patch.
