Hello,

This is my first attempt at submitting a patch, so keep that in mind
in case I messed up somewhere.

I already did the copyright assignment dance and it was accepted &
sent to me the 2016-09-07, do I need to send the confirmation to
someone in order to post here?

Just to be sure, I should send emails to emacs-devel as plain text
right? no html?

Anyway, back to the subject: this patch removes the variable
`command-debug-status', which really seems to be unused since a long
time to me (that's what "git -G Vcommand-debug-status" says).

I fell on it while looking to solve another problem (which will be
discussed in another email).

Thanks,
Philippe
