Bug 2294

Hi.

AFAIU, using (multiple) tabs in e.g. sshd_config or ssh_config works, e.g. one can justify one's options like this:
AddressFamily   any
Port            22
ListenAddress   localhost
by having (multiple) tabs and/or (multiple) spaces between directive and option or between two options.


I tried to do the same on known hosts files,... after having a very short glance at hostfile.c it thought it would work,... but apparently it does not.
host.example.org,host ecdsa-sha2-nistp521 AAA...
host.example.org,host ssh-rsa             AAA...
foo                   ssh-ed25519         AAA...

apparently it still works to have a tab between hostname(s) filed and algorithm,... but when there is one or more tabs between algo and key data,... ssh apparently no longer recognises that line and asks me to verify the fingerprint.


Now I don't know whether this is expected to work (and a bug), or whether it's not expected to work.... than this could be an request for enhancement,... i.e. in all places where one space is allowed as a field separator, multiple tabs and/or spaces should be allowed as well.


Oh and should this ever be made working,... I've just seen that bash-completion fails miserably when having (multiple) spaces/tabs in the known hosts files, it even suggests th algos and the key material as a completion target... so one should then probably report a bug there as well, to have that fixed.


Cheers,
Chris.
