LST generates wrong bytes for non-alphabetic characters

[leesaudan2]

According to the docs, the LST command should only generate byte values between $40 and $7F, inclusively. However, it is WRONGLY generating byte values $20--$3F instead of $60--$7F. Values between $40--$5F are properly generated, though.

Attached is a test file test1.s, which when assembled with the "-V" option, gives the attached
test1_Output.txt.

I'm using Merlin32 v1.0, Linux64 precompile binary from the downloaded zip file.
