Here is something else I'd like to get into core:

- given a remote repo object (or a string!) return the alias

For example, given 'https://sean@smf.io/hg' return 'smf' (which is a
path alias in my hgrc)

- compare a scheme with a uri

If I define 'smf://' to be 'https://sean@smf.io/' then I'd want a way to
compare 'smf://hg' == 'https://sean@smf.io/hg'
