It was unfortunate that these functions were not already documented.
But now that you are elevating them from static to global functions, it
would be great if you would add some comments for them.

(By the way, thanks for the docstrings that you added in an earlier patch.)

This patch is not only moving code around, but also:

* extracting a new function, validate_path()

* changing the signature of validate_pathspec()

* maybe other things?  How is a reviewer to know without examining every
line of the patch?

Each self-contained change should be done in a separate patch.  For
example, one patch should move the code while making only the minimal
changes logically connected to the move (e.g., removing "static"
qualifiers).  The other changes should be made separate commits.
