Catch an APS1 error when merging marker data creates a short waveform.
Catch an APS1 error when merging marker data creates a short waveform.

Happens when two marker blips are very close together (e.g. 12 samples) and
splitting a TA waveform to place the blips. Then the fact that marker data has
to have non-zero count causes the creation of an 8 sample waveform, which is too
short.
