[ruby-core:80456] [Ruby trunk Bug#13315] Single "%" at the end of `printf` format string appears in the result

ruby-core #80456
Issue #13315 has been updated by morishin (Shintaro Morikawa).
I believe this is not intentional, so created a pull-request on GitHub.

----------------------------------------
Bug #13315: Single "%" at the end of `printf` format string appears in the result
https://bugs.ruby-lang.org/issues/13315#change-63948
* Author: nobu (Nobuyoshi Nakada)
* Status: Open
* Priority: Normal
* Assignee:
* Target version:
* ruby -v:
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
Is this intentional?
```ruby
printf("%") #=> "%"
```
`printf` in glibc does print nothing, gcc warns though.
```c
#include <stdio.h>
int main(void)
{
printf("%");
return 0;
}
```
```sh
$ gcc fmt.c && ./a.out
fmt.c: In function ‘main’:
fmt.c:5:10: warning: spurious trailing ‘%’ in format [-Wformat=]
printf("%");
^
```
`printf` command of bash errs.
```sh
$ printf "%"
-bash: printf: `%': missing format character
```
