Honor MANSECT and -S section-list when matching section names
man(1) relies on the default list of manual sections when determining whether
an argument is a section name, completely ignoring the MANSECT environment
variable and the sections listed in the argument to the -S option.
I encountered this behavior when trying to determine why
man -S '1:3p' '3p' printf
would open printf(1) instead of printf(3p) after installing man-pages-posix[1],
yet
man -S '3p' printf
worked correctly.
Attached is a patch that ensures the section list provided by either the -S
option (which sets the MANSECT shell variable) or the MANSECT environment
variable is searched if they don't expand to an empty string, else the default
section list is searched. It intentionally avoids setting the MANSECT shell
variable since that's taken care of later by the man_setup() function.
