I disagree. This comment is a modified version of the comment for
`vc-default-ignore'. And the exact same phrase also pops up for
`vc-svn-ignore':

vc.el:1420:FILE is a file wildcard, relative to the root directory of DIRECTORY.
vc-svn.el:356:FILE is a file wildcard, relative to the root directory of 
DIRECTORY.

Also `top level' only appears twice in the `vc-' files:

vc-bzr.el:1070: A merge has been performed.\nA commit from the top-level 
directory
vc-cvs.el:904:;; at the top level for CVS.

while the phrases `root', `root directory', `repository root'
appear 23 times in strings and comments alone.

The sentence is actually utterly false for `vc-default-ignore',
since FILE is usually an absolute file path when called from a
*vc-dir* buffer. With relative paths the code is still wrong and
ends up as plain basename for the pattern.

Since the implementation of `vc-hg-ignore' corresponds to the
actual situation, I have changed the wording to reflect that using
the term `project root'.

Done.

I agree, and I fixed the remove option, so it actually does what
it says ;-)

You're welcome.

Oops, I had forgotten to include the variable
`vc-hg-ignore-detect-wildcard'. So here is an overhauled patch.
