Handle .br - this makes processing of the netbsd-4
src/dist/bzip2/bzip2.1 file work:
Before:
% getNAME /usr/cvs/src-4/dist/bzip2/bzip2.1
bzip2, bunzip2 (1) - a block-sorting file compressor, v1.0.2 .br bzcat (1) - decompresses files to stdout .br bzip2recover (1) - recovers data from damaged bzip2 files
After:
% getNAME /usr/cvs/src-4/dist/bzip2/bzip2.1
bzip2, bunzip2 (1) - a block-sorting file compressor, v1.0.2
bzcat (1) - decompresses files to stdout
bzip2recover (1) - recovers data from damaged bzip2 files
Verified with code from src/share/man/man0 that nothing else was
broken by this change.
