hg: make _local() behave consistently on Python 3.8 (issue6287)
Python 3.8 makes os.path.isfile quietly eat "path invalid" errors and
return False instead of allowing the exception to propagate. Given
that this is a change from 2018 (sigh) and it's mentioned in the
release notes (double sigh) we're definitely too late to complain to
Python about the behavior change, so open-code part of
os.path.isfile() in this method so we can catch invalid-path errors
and handle them appropriately. I confirmed that posixpath and ntpath
both delegate to genericpath, which uses os.stat() under the covers.
