bug#65007: [PATCH] Allow displaying program IO in the GDB buffer.

[StrawberryTea]

Hi Po Lu,

I’m not sure whether I should reply or always send the edited patch in as a 
separate email and have been emailing several times but no longer getting 
responses. I made the changes you requested:


lisp/progmodes/gdb-mi.el (gdb-use-io-buffer): Don’t create IO
═════════════════════════════════════════════════════════════

buffer if `gdb-use-io-buffer’.
(gdb-use-io-buffer): New user option.
