#169 /Sg listings are unusable

[paul]

in JWASM v2.06e the listing file generated with /Sg enabled is corrupted for dot-directive lines (eg .if, .while, .repeat, etc).
It seems the generated code overlays the source comment area of the dot-directive line, after the first comment character.
As an example (small file compiled wit /Sg /Sn /Fl ):

Confirmed.

the -Sg listing is messed up if a line containes both a comment and a directive that generates source lines ( invoke, hll directives, ... )

Fixed in v2.07.
