Subject: config: add Host option "ssh_user"
X-Git-Url: https://ruderich.org/simon/gitweb/?p=safcm%2Fsafcm.git;a=commitdiff_plain;h=023e863fbd9c6cf5bebd18e19c05ae9e60fbbe21

config: add Host option "ssh_user"

If it's empty or not present the default user of `ssh` is used. This is
either the current user or the user configured in ~/.ssh/config.
