+This option does not make a new connection; instead it allows testing
+for the presence of an existing connection that can be shared.
+(See \k{config-ssh-sharing} for more information about SSH connection

+normally use with Plink to make an actual connection (a host/port
+number, a bare saved session name, \c{-load}, etc). It returns a
