It would? I was under the impression that -stack-info-depth would return
the number of frames on the stack without taking what the current frame
is into account.

-stack-info-depth
^done,depth="3"
(gdb)
^done depth 3

-stack-info-frame
^done,level="0"
(gdb)
^done level 0

up
^done,frame={level="1 ",addr="0x080484a8",func="main",args=[{name="argc",value="1"},{name="argv",value="0xbffff5c4"}],file="resources.c",line="38"},line="38",file="resources.c"

-stack-info-depth
^done,depth="3"
(gdb)

-stack-info-frame
^done,level="1"
(gdb)

I can't speak as to the original design goals. The existing documentation
for the command is not very clear about what it should do. I just
thought -stack-info-frame would work like -stack-select-frame in
that it would deal with an integer stack level. How is one meant to
query the stack level?
