Indexing and searching non-numeric sections with apropos(1)

[Abhinav Upadhyay <er.abhinav.upadhyay%gmail.com@localhost>]

Hi All,

With bin/51062, makemandb(8) can index non-numeric sections and also
apropos(1) can now accept non-numeric sections for querying. That
means you do queries like

apropos -s 9lua systm
apropos -s n foo bar

To be able to use this feature, you need to regenerate the database.
You can do this by running makemandb -f manually.

If you don't regenerate the database, it will not cause any problems
(except that you cannot query non-numeric sections).
