Thanks for the patch.

What is the use case?  I mean, if one wants only the numeric numbers,
then this is usually in a script for automatic processing, and then
I thinks it's clearer to have uid and group/groups separated:

  $ id -u
  1000

  $ id -g
  100

  $ id -G
  100 454 457 480 492

There's even a -z option to separate by NULs instead of white space.

And, when still needing all in the same output, one could filter like e.g.:

  $ id | sed 's/([^)]*)//g'
  uid=1000 gid=100 groups=100,454,457,480,492

So I'm currently 40:60 to add it.

Thanks & have a nice day,
Berny
