monospace versus preformated text

[vitsoft]

The monospace button visible when a message is posted didn't keep spaces at the beginning of line.
I created new button pre which should be more appropriate for posting code samples with indention.
Testing monospace:
Sample PROC
PUSHAD
; some code with indentation.
POPAD
RET
ENDP Sample

and now the same sample as pre:

Sample PROC
              PUSHAD
                 ; some code with indentation.
              POPAD
              RET
           ENDP Sample
