This runs an interactive shell session on the host, rathern than
running `sh -c ""' on it.
Evidently ssh checks for the presence of a command line specification
after (foolishly, but now historically unavoidably) concatenating all
the command line arguments with spaces in between.
Turn ssh host "" into ssh host " " which is the expected no-op.
