527ec39 (generate-cmdlist: parse common group commands, 2015-05-21) replaced generate-cmdlist.sh with a more functional Perl version, generate-cmdlist.perl. The Perl version gleans named tags from a new "common groups" section in command-list.txt and recognizes those tags in "command list" section entries in place of the old 'common' tag. This allows git-help to, not only recognize, but also group common commands. Although the tests require Perl, 527ec39 creates an unconditional dependence upon Perl in the build system itself, which can not be overridden with NO_PERL. Such a dependency may be undesirable; for instance, the 'git-lite' package in the FreeBSD ports tree is intended as a minimal Git installation (which may, for example, be useful on servers needing only local clone and update capability), which, historically, has not depended upon Perl[1]. Therefore, revive generate-cmdlist.sh and extend it to recognize "common groups" and its named tags. Retire generate-cmdlist.perl.
