Currently follow-fork is yes or no and detach-on-fork is yes or no.
It seems to me that it would be clearer if there was only one, with
three states "parent", "child", "both".
Feel free to flame me if this has already been talked to death.

(gdb) set follow-fork-mode yes
Undefined item: "yes".
(gdb) set follow-fork-mode no
Undefined item: "no".
(gdb) help set follow-fork
Set debugger response to a program call of fork or vfork.
A fork or vfork creates a new process. follow-fork-mode can be:
parent - the original process is debugged after a fork
child - the new process is debugged after a fork
The unfollowed process will continue to run.
By default, the debugger will follow the parent process.
Once upon a time, there was a "both" item in this menu. It was
supposed to spawn two GDBs, one attached to each. I think
set detach-on-fork off is a reasonable behavior for "set follow-fork
both". Michael, how about you?
