I don't object, but this has a disadvantage that we would need to
start using this regexp-based variable right away, to filter out only
literally the ".cvs", ".bzr", ".git" etc. directories, not just any
directory that ends in these extensions.  IOW, introducing the new
variable would mean that the default value of
completion-ignored-extensions will change and the default value of the
new variable will be non-nil.  So it sounds like a more invasive
change.
