Subject: bug#1490: 23.0.60; C-d sends "\n" while debugging with gdb in Emacs

While in the gdb of Emacs ...
  (gdb) set var retp = fgets(buf, 32, stdin)
                                          <--- I typed C-d here
without typing RETURN
  (gdb) p retp
  $4 = 0xffe1e58c "\n"
  (gdb) set var reti = getchar()
                                          <--- I typed C-d here
without typing RETURN
  (gdb) p reti
  $6 = 10

But in pure gdb
  (gdb) set var retp = fgets(buf, 32, stdin)
  (gdb) p retp
  $1 = 0x0
  (gdb) set var reti = getchar()
  (gdb) p reti
  $2 = -1
  (gdb)

Emacs sends extra '\n' character when i type C-d in debugger mode
