            Bug ID: 30522
           Summary: [gdb/tui] Entering singlekey mode doesn't clear
                    partial command line
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: tui
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

Say we start gdb in TUI mode:
...
$ gdb -q -tui ./a.out 
...
we get in the command window (X marks blinking cursor):
...
Reading symbols from ./a.out...
(gdb) X
...

Now let's type "sun":
...
Reading symbols from ./a.out...
(gdb) sunX
...
and do C-x s to enter singlekey mode:
...
Reading symbols from ./a.out...
sunX
...
and then press d.  We get:
...
Reading symbols from ./a.out...
sun
Undefined command: "sundown".  Try "help".
X
...

I think when entering singlekey mode we probably want to clear the partial
command line.

    [gdb/tui] Delete line buffer when switching to singlekey

    Say we're in TUI mode, and type "sun":
    ...
    (gdb) sun
    ...

    After switching to SingleKey mode using C-x s, we have just:
    ...
    sun
    ...

    After typing "d", we get:
    ...
    sun
    Undefined command: "sundown".  Try "help".
    ...

    The SingleKey "d" is supposed run the "down" command.

    Fix this by clearing the readline line buffer when switching to SingleKey
    mode.

    Tested on x86_64-linux.
