FBG * option not working as expected

[phillipeaton]

At the start of a source file, if I have...

      ORG $5000
MLIST RMB 2048

      ORG $6000
<SOME MORE CODE TO $6FFF>

...the assembled binary output file is 4k in size, not 8k, i.e. from $6000 onwards, the 4k block starting at $5000 doesn't get created, presumably because no code is laid down.

It's fairly easy to workaround, but the output was unexpected.

With this test sample, I found bytes are padded in the binary output, but not the listing or S19 output file. The fill value appears to be always $00
