Hm. I can't. It seems to work:

    logtail -f <LOGFILE> -o <OFFSET>	    # works (according man page)

.. as documented. I think last time I supposed it should work that way
too:

    logtail -o <OFFSET> <LOGFILE>	    # doesn't work (doesn't fit
					      to manpage)

    logtail <LOGFILE>			    # works (but doesn't fit to manpage)
					    # but of course, no
					    # alternative offset file



So there is some inconsistency between the tool and the manpage.

Since I believe the last invocation is naturally, the last but one
should work too, shouldn't it? The first invocation is the only valid
(at least according to the man page)

And according to the source following works too:

    logtail <LOGFILE> <OFFSET>



I'll attach 2 diffs, both seem(!) to work for me. But I didn't touch the
man page so far.
