Emacs and VC AKA Version Control and an excessive list of handled backends — the 2016-01 update

I just remembered, how many file checks Emacs’ VC library does, if you don’t cut down its list vc-handled-backends. For every single backend listed there “we” are doing a “repository check”.

My Jenkins guru Nathan pointed me to this plugin.
