If you do an M-x man keyword search with nothing matching, like

    M-x man
    -k jkjkjkjk Ret

The result shown is

    error in process sentinel: Can't find the -k jkjkjkjk manpage

where reads as if it thought the "-k" was the page name -- which is not
the case, M-x man understands -k is an "apropos" keyword search.

This could be due to "man-db" (as used in debian and elsewhere) printing
nothing for no matches, as opposed to a "nothing appropriate" message
which Man-bgproc-sentinel knows to look for.

Perhaps something along the lines below,

2009-12-07  Kevin Ryde  <address@hidden>

        * man.el (Man-bgproc-sentinel): When "-k foo" produces no output
        show error "no matches" rather than "Can't find manpage", as the
        latter reads like -k was interpreted as a page name (which is not
        so).
