Fix postprocess convert command for alpha channels

Browse Source 
On occasion the author would save his image as a .gif with transparency
when he (most likely) intended to leave the parts white. This was
already accounted for in the `convert` command, but the wrong flags were
being used. This should be fixed now (compare strip from 2002-09-11)
