I am not sure I understood. I did not put the bug number in the subject at all,
it is probably done by debbugs. E.g. if you look at this v2 patch in a browser
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=61490#20 the "Subject" line
displayed there does not contain a bug number.

I can add a bug number to the body the next time, but I'm not sure it would make
debbugs stop adding the prefix.
