Re: Patch to make VC annotate async

[Stefan Monnier <monnier@iro.umontreal.ca>]

For the vc-cvs.el part of the patch , can you try the patch below?
Also I noticed that my own version used vc-exec-after because that makes it
work both for async and sync and I select between the two with

  (if (and (vc-stay-local-p file) (fboundp 'start-process)) 'async 0)

Not sure if it matters.
