Subject: Fix build failure when compiling in release
Compiling with --buildtype=release fails with message:
../main.c:935:17: error: argument 2 null where non-null expected [-Werror=nonnull]
935 | memcpy(state->text + state->cursor, s, n);
GCC only produces this error with optimizations enabled. Looking at
the build output I assume this happens because it tries to inline the
function.
