Summary0001223: Notes in .XM get triggered after key-off when doing portamento-to-note without instrument number

In the attached module, on channels 1-2 of pattern 2 in position 7 (for example), the F and A notes have their volume envelopes reset when they should only be doing portamento-to-note on the decaying notes from the previous pattern.

Secondly, if I start playback from this pattern, the notes are still very much audible when they really shouldn't have been triggered at all. The only way I can silence them is by deleting the prior positions 0-6 placing pattern 2 at the beginning where there can't be a prior instrument reference. However if this behavior is intentional, I do see the workflow convenience benefits in it.

TagsNo tags attached.
Has the bug occurred in previous versions?I've heard this playback error on several Android music players. Droidsound-E reports libopenmpt v0.4.3
Tested code revision (in case you know it)

Secondly, if I start playback from this pattern, the notes are still very much audible when they really shouldn't have been triggered at all.

(lib)OpenMPT keeps track of active notes using a simplified parser when jumping around in the module but I guess this parser might not be taking Key-Off effects into account. I'll look into it (and the other issue).

Alright, the easy part (hanging notes when seeking) is fixed in r11567.
