You can either see autocompletion or argument list. It's especially annoying when using e.g. `Input.get_vector()` method which has multiple arguments difficult to remember.

### Steps to reproduce

1. Write `Input.get_vector(`
2. Remove `(`
3. Add `(`

### Minimal reproduction project

same_line = true;
					in_region = d;
					delimiter_cache.write[i][from + 1] = d;
					from += start_key_length;
					
					if (end_key_length == 0 || delimiters[d].line_only || from + end_key_length > line_length) {
						j = line_length;
						if (delimiters[d].line_only) {
							delimiter_cache.write[i][line_length + 1] = -1;
						} else {
							end_region = in_region;
						}
					}
					break;

				if (j == line_length || in_region == -1) {
					continue;

			int end_key_length = delimiters[in_region].end_key.length();
			const char32_t *end_key = delimiters[in_region].end_key.get_data();
			for (; from < line_length; from++) {
				if (line_length - from < end_key_length) {
