In your rewrite below, this is still lacking, I think.

Here, you say "correctly interpret relative path later on", but it
is not made clear why it is even necessary.  And that makes ...

... "cannot resolve the relative path correctly" above sound like a
bug in remote-hg.  Something like:

    Cloning a local hg repository using a relative path, e.g.

      git clone hg::hgrepo gitrepo

    stores "hg::hgrepo" in gitrepo/.git/config as its URL.  When
    remote-hg is invoked by "git fetch", it chdirs to X (which is
    different from the "gitrepo" directory) and uses the URL (which
    is not correct, as it is a relative path but the cwd is
    different when it is used) to interact with the original
    "hgrepo", which will fail.

is needed, but you didn't explain what that X is.  Perhaps it is a
temporary directory.  Perhaps it is a hidden Hg repository somewhere
in gitrepo/.git directory.  Or something else.

With that explained ...

... the description of the fix start making sense, but not without.

You did nothing wrong, other than not having given the necessary
context to understand how the change flowed here and it is kosher.

Which you now have, so it is OK.
