That was my first reaction but there are places where "hostname"
already gives a name that is not "short" at all, without being
invoked with "-f".

For example, the (virtual) workstation I am typing this message on
sits in a $WORK datacenter, where "hostname" gives the same string
as "hostname -f", which looks like "git.c.xxxxxx.tld" ("git" is the
only part I picked myself for it, "c" is shared by those employee
workstations hosted at datacenters, "xxxxxx.tld" is redacted to
conceal the real domain name to protect the culprits ;-).

I think the most honest answer we can give in the documentation is
that we use what gethostname() [*] gives.
