Sure, zlib and parts of gzip were written by JLG and Mark Adler using a close 
variant of the "new" BSD license.  Depending on where you get your gzip from, 
add some public domain software (compress) and/or some GPL'ed code (mainly for 
the longopt calls like --best or --verbose).

Does this affect whether adding bzip2 support to man is a good idea?

OK.  So there may be a pure BSD-licensed gzip handy, in addition to the one 
from the FSF.  At the risk of distracting you from the licensing issues, 
fascinating as such things may be, would you care to express an opinion on the 
PR?  :-)
