inotify should notify it somehow, but I haven't checked to say it for
sure.

IMO, a good solution actually is to return from `tail_forever_inotify'
as soon as a remote file appears and enter `tail_forever'.  The
disadvantage is that there is no way to return back to the inotify
backend when the file path becomes local again, but I don't really think
this scenario is going to happen often.

I am also thinking of a tail refactoring and merge the poll based
backend with the new inotify backend, having the possibility to handle
different files with different mechanisms, it will solve the stdin
problem too.  I hope to have soon some time to look at it.

Cheers,
Giuseppe
