After pondering on this for a while and discussing it with others in
the gdb group, I am inclined to accept this patch into the main line
but not 5.1.

The possibility that there is an identifier that start with a
isspace() char is quite remote. And as Jason points out the rest
of the code in the function wouldn't be able to deal with it either.

Jason, if you can check this in, please go ahead.

Looking at this function I also noticed an outdated comment. Will fix
in a follow up patch.
