+ building test-packages for Arch.
+ + modify configure script to avoid conflict with a non-POSIX feature

+ + modify tracemunch to accept filename parameters in addition to use
+ as a pipe/filter.
+ + minor optimization to reduce calls to _nc_reserve_pairs (prompted by
+ discussion with Bryan Christ).
+ + add test/pair_content.c and test/color_content.c
+ + modify infocmp to omit filtering of "OTxx" names which are used for
