confused about diff

[Alexis S. L. Carvalho]

Thus spake Neal Becker:

> hg diff ssh://laptop/repos
> 
> (nothing)

Note that the arguments to diff are filenames, not a repository, so
mercurial should probably print something like "ssh://laptop/repos: No
such file or directory".

You could specify a different repository using the -R/--repository
global option, but that also doesn't (currently?) work:

$ hg -R http://selenic.com/hg/ diff
