It's required if both HUSH_SHELL _and_ MENU are selected. The code in
common/menu.c looks like this:
if (IS_ENABLED(CONFIG_SHELL_HUSH)) {
process_escape_sequence(m->display,
m->display_buffer,
m->display_buffer_size);
puts(m->display_buffer);
} else {
puts(m->display);
}
Thus, the configuration needs to say, if you turn on MENU (enabling
menu.c), then select PROCESS_ESCAPE_SEQUENCE if HUSH_SHELL is also
selected (because it will try to call process_escape_sequence()).
As I described in my other email, it's very easy to create a test case
which does not build.
Keep in mind, I'm talking about making a Kconfig which is correct for
the code as the code currently is. Maybe in the opinion of some (you?),
it is the code that should be different, not the configuration. If you
or someone else has a better idea how to fix this, that would be fine
too. Right now however, it is broken.
Alan.
