Git.Remote.parseRemoteLocation had a hack to handle URIs that contained
characters like spaces, which is something git unfortunately allows
despite not being a valid URI. However, that hack looked for "//" to
guess something was an URI, and these gcrypt URIs, being to a local
path, don't contain that. So instead escape all illegal characters and
check if the resulting thing is an URI.
And that was already done by Git.Construct.fromUrl, so
internally the gcrypt URI with a space looks like "gcrypt::foo%20bar"
and that needs to be de-escaped when converting back from URI to local
repo path.
This change might also allow a few other almost-valid URIs to be handled
as URIs by git-annex. None that contain "//" will change, and any
behavior change should result in git-annex doing closer to a right thing
than it did before, probably.
