Add support for \aa, \AA, \lq, \rq, \lbrack, \rbrack (#1069)

Browse Source 
* Add support for \aa, \AA, \lq, \rq, \lbrack, \rbrack

The lack of \aa and \AA was reported in #1066.  Added these
via simple macros, with supporting tests.  Also add \lq, \rq,
\lbrack, \rbrack as aliases for "`", "'", "[", "]" which were
in the same area of latex.ltx.

* removed duplicate comment
