'main': Parameter expansions may not contain assignments.

Browse Source 
In «a="b=c"; $a», the '=' sign in the expansion of $a is not active.
Therefore, prevent the expansion of $a from being considered an
assignment.  Update test expectations accordingly.

As a side effect, this prevents line 836 from firing for the cases in
these two tests, thereby fixing the double $region_highlight addition
(see log message of the previous commit).  That leaves the line 966
addition.  However, the double addition remains a latent bug (see
discussion in PR #684).
