Fix crash on listing when nested noexpand macros are used Macros flagged noexpand were causing a segfault during listing. The problem was incorrect accounting for nesting levels for noexpand macros causing the listing handler to fall off the end of the program in certain circumstances and in other circumstances it would fail to suppress expansion. Both the segfault in the case of misbehaviour and the misbhaviour itself are corrected with this update. If you do not use nested noexpand macros, this bug has no effect.

>LWASM supports all documented MC6809 instructions as defined by Motorola. 
It also supports all known HD6309 instructions.  While there is general
agreement on the pneumonics for most of the 6309 instructions, there is some
variance with the block transfer instructions. TFM for all four variations
seems to have gained the most traction and, thus, this is the form that is
recommended for LWASM. However, it also supports COPY, COPY-, IMP, EXP,
TFRP, TFRM, TFRS, and TFRR. It further adds COPY+ as a synomym for COPY,
IMPLODE for IMP, and EXPAND for EXP.</P
><P
>By default, LWASM accepts 6309 instructions. However, using the
<CODE
CLASS="PARAMETER"
>--6809</CODE
> parameter, you can cause it to throw errors on
6309 instructions instead.</P
><P
>The standard addressing mode specifiers are supported. These are the
hash sign ("#") for immediate mode, the less than sign ("&lt;") for forced
eight bit modes, and the greater than sign ("&gt;") for forced sixteen bit modes.</P
><P
>Additionally, LWASM supports using the asterisk ("*") to indicate
base page addressing. This should not be used in hand-written source code,
however, because it is non-standard and may or may not be present in future
versions of LWASM.</P
