8 # and real) group names (not ids). The known commands are:

13 # Beware 2: id -Gn or id -a format might be id(name) or name(id).
14 # Beware 3: the groups= might be anywhere in the id output.
15 # Beware 4: groups can have spaces ('id -a' being the only defense against this)
16 # Beware 5: id -a might not contain the groups= part.

20 # foo bar zot # accept
21 # foo 22 42 bar zot # accept
22 # 1 22 42 2 3 # reject
23 # groups=(42),foo(1),bar(2),zot me(3) # parse
24 # groups=22,42,1(foo),2(bar),3(zot me) # parse
26 # and the groups= might be after, before, or between uid=... and gid=...
