(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. (My
bug#5431.)
* man.el (man): Revise docstring a bit to show -a and -l as
examples. Add -k description since support for it has otherwise
been a secret. (Further to bug#3717.)
