Description
With CheckOverlapping=False, even when the spectrum numbers do not overlap, they are changed. They should only be fixed if they overlap and CheckOverlapping=False
Load(Filename=r'CNCS_7860_event.nxs',OutputWorkspace='CNCS_7860_event')
CropWorkspace(InputWorkspace='CNCS_7860_event',OutputWorkspace='CNCS_7860_event_top',EndWorkspaceIndex='1000')
CropWorkspace(InputWorkspace='CNCS_7860_event',OutputWorkspace='CNCS_7860_event_bottom',StartWorkspaceIndex='1001',EndWorkspaceIndex='2000')
ConjoinWorkspaces('CNCS_7860_event_top','CNCS_7860_event_bottom', CheckOverlapping=False)
This is a problem for the ISIS C2E which currently expects the monitors to be in with the data

The spectrum numbers are only "fixed" if they don't not already overlap.

Confirmed that spectrum numbers are not changed when running the script above, and that they were before the changeset above. If the spectrum numbers do overlap, and CheckOverlapping is False, then renumbering does take place - with a big gap for some reason.
The wiki is out of date on this algorithm. I will try and update it to the best of my knowledge.
