Step outer function call

["William K. Foster" <wkf@sinavigator.com>]

Hello,

I often find that when stepping through code, I would like to step into 
the outer most function call on a line of code, but the only way I see 
to do this is to step into each inner call and finish them until 
reaching the outer call.  For example:

  foo(bar(), baz());

If on the above line and I step, I first enter bar(), then baz(), and 
finally foo().

The vast majority of the time, I want to enter foo().

Is there a command or script to accomplish this?

If not, is this a reasonable feature request for gdb?

Thanks.
