--- Comment #9 from Tom de Vries <vries at gcc dot gnu.org> ---
Fixed by commit in the in-repo copy of readline.

The problem is still there for system readlines that miss this patch, but
AFAICT there's nothing we can do about this in gdb.

That is, maybe we could fix half of the problem by not returning '\0' to
readline, but instead call tui_getc_1 in a loop until it returns something =
not
'\0'.  But the other half of the problem would still exist and cause the sa=
me
problem.
