Subject: Re: [darcs patch] filepath: normalise trailing dot

Hi,

I've re-opened ticket #3975 related to this proposal.

It's a fairly minor patch which ensures that filepaths containing a
trailing dot are normalised consistently, ie. the path "foo/bar/." is
normalised to "foo/bar"

Discussion period: 2 weeks

cheers,

Conrad.
