>Description:
the new apropos offers search in sections 1 through 9 only. 'n' is another 
section, typically used in e.g. tcl man pages. apropos -s n isn't working:

$ apropos -s n expr
apropos: Invalid section

Two things: 
1) it could say "Invalid section 'n'"
2) it should accept 'n' as a valid section
