warn_on_inaccessible(): a helper to warn on inaccessible paths
The previous series introduced warnings to multiple places, but it could become tiring to see the warning on the same path over and over again during a single run of Git. Making just one function responsible for issuing this warning, we could later choose to keep track of which paths we issued a warning (it would involve a hash table of paths after running them through real_path() or something) in order to reduce noise. Right now we do not know if the noise reduction is necessary, but it still would be a good code reduction/sharing anyway. Signed-off-by: Junio C Hamano <gitster@pobox.com>
