Like I said, I do not have a particular use for it, but I don't think it
would hurt anybody who does not use it. If you want to polish it up into
a real patch with docs and tests, I don't mind.

The only downside I can think of is that we might want to use the
subsection in "include.SUBSECTION.*" for some other limiting conditions
(e.g., "only include this config when running version >= X.Y", or even
"include only when environment variable FOO is true").

I guess we could do something like:

  [include "repo:...your regex here..."]
    path = .gitconfig-only-for-some-repos
  [include "env:USE_MY_MAGIC_CONFIG"]
    path = .gitconfig-only-when-magic-env-set

Adding the "repo:" prefix for this repo-dir matching is pretty trivial.
Adding a similar env-matching is only slightly less trivial; but does
anybody actually want it?
