Fix todo-mode item insertion bug (bug#70937)

it as invalid for item insertion, thus preventing mistakenly
pressing a key from executing an unwanted different todo-mode

There’s no need for the caller to convert to int16_t, and using
int makes the machine code a bit smaller (and presumably a bit

unsigned long long int rather than uint32_t and uint64_t, as POSIX
does not guarantee the presence of uint64_t, and uint32_t and
uint64_t both in theory have problems with undefined behavior on
integer overflow.  This doesn’t affect behavior (or even machine
code) on typical platforms.
