It wouldn't be impossibly hard to add
POPT_ARGFLAG_COMMALIOST
as an option modifier permitted into POPT_ARG_ARGV/POPT_ARG_BITSET
and just add a split sloop for strings passed to those options.
todo++ … but likely months before releasing POPT with POPT_ARGFLAG_COMMALIST,
and years before any distro bothers to upgrade POPT, judging from
RHEL6's and Fedora's "Fork y'all!" insistence to never use any
code I've touched (both RHEL6/Fedora continute with popt-1.13
years after release.)
