Summary	0000242: XM effect works while it shouldn't
Description	In the XM format, the Axy command does Volume Slide. When you write in AF1, it actually recognizes this as the IT equivilant: DF1, which is a fine volume slide. This effect however does not exists in XM. In XM one would use EAx and EBx instead. So Whenever someone uses DF1 or D1F, modplug should completely ignore the effect, like other trackers to remind people that they'd need another effect.
Steps To Reproduce	Write a pattern with a sample playing at full volume, and give it AF1 volume slide. Volume should stay normal.
Additional Information	MadTracker will ignore AF1 completely, and according to the specs, its an invalid combination. Even the right-click menu in OpenMPT has it right!
Tags	No tags attached.

Has the bug occurred in previous versions?
Tested code revision (in case you know it)

Of course that's still wrong, but not the same as your described.
