Thank you for the patch.  I will try to get that integrated sometime today.  I'll be traveling for the next few days and will have limited ability during that time to address further concerns.

Automatic vs. manual reset were based on my thinking about whether the function WCMD_ctrlc_status would be called more than once per command iteration.  If called only once then ownership of the status passes to the caller and thus automatic reset is cleaner.  However, thinking further about this, it probably makes sense to switch back to manual reset, in case future callers (i.e. perhaps for different internal commands, etc.) might want to call it more than once per iteration.  That, and the fact that there is a manual reset anyway before command launch in the loop toward the end of wmain suggests that a manual reset would be better, so I will switch back when I submit the changes containing your patch.
