bug#36911: 26.1; Impossible to customise vc-ignore-dir-regexp

[Juliusz Chroboczek]

I'm trying to disable vc in a directory (an sshfs mount).  The obvious
candidate is vc-ignore-dir-regexp:

> vc-ignore-dir-regexp is a variable defined in ‘vc-hooks.el’.
> Its value is
> "\\`\\(?:[\\/][\\/][^\\/]+[\\/]\\|/\\(?:net\\|afs\\|\\.\\.\\.\\)/\\)\\'"

It is essentially impossible for a normal user to customise this variable
without disabling the existing functionality.  So for now, it's

  (setq vc-handled-backends nil)

I'm not sure why it's impossible to customise that variable?  You can
just set it to "/my/ignored/directory" and that should work.

(You'd lose the original value, which is about AFS and SMB mounts, which
may be a sensible default, but which isn't relevant to most people
working in GNU/Linux.)

How am I supposed to know that?  I'm sure I'm not the only person afraid
to touch it.

It does look pretty daunting as it is, but it's just a regexp to ignore
files and you can put whatever you want in it.  And I don't think that's
unclear from the doc string, so I don't think there's anything to fix here.
