Seems to work very well. Excellent! There is one thing that is a bit
strange, though. Unless I explicitly list my home directory as one of the
remote paths, acme simply does not connect to the remote machine at all. No
big deal, though.
Another slight issue is that because acme loads whole files, opening a huge
file may take quite a bit of time. Sam avoids this issue by only loading
the file on the remote, and transfers only what is needed to refresh the
display. But that's just a different tradeoff. All in all I think I prefer
your acme, especially since it can run acme-lsp on the remote.
