Fix the "ssh://" protocol to prevent an attack whereby the attacker
convinces a victim to run a "clone" with a dodgy URL and thereby gains
access to their system.

From https://www.fossil-scm.org/xfer/info/1f63db591c77108c
...
Fix the SSH sync protocol to avoid "ssh" command-line option injection
attacks such as those fixed in Git 2.14.1, Mercurial 4.2.3, and Subversion 1.9.7.
As "ssh://" URLs cannot be buried out of sight in Fossil, the vulnerability does
not appear to be as severe as in those other systems
Fixed in 2.4
