Thanks for the explanation.

Some bits are missing,

 - A test case, in which we can define some reggroups "foo" and test
   expected "foo" is shown in the output of "maintenance print
   reggroups".  You can add reggroups in gdb.xml/extra-regs.xml.

 - A test case with live inferior, get a list of support reggroups from
   the output of "maint print reggroups", pass each reggroup to "info
   reg $group", and test there is no error.

 - Document "info registers".
   https://sourceware.org/gdb/current/onlinedocs/gdb/Registers.html
   doesn't document the usage "info reg GROUP".  We need to add it.

 - Add a news entry, because your patch adds a user visible change.
