mdocml: Only focus on the query input box when no manual page is

[schwarze@mdocml.bsd.lv]

Log Message:
-----------
Only focus on the query input box when no manual page is displayed,
that is, for the index page, for the noresult page, and for the
result of an apropos(1) query with more than one page.
As noted by bentley@, when a manual page is displayed, it is more
important that people can quickly use the space bar for paging and 
Ctrl-F for searching.
