scanf.3: Clarify ll and L modifiers
Relevant documents:
POSIX:
<https://pubs.opengroup.org/onlinepubs/9699919799/functions/fscanf.html>
glibc:
<https://www.gnu.org/software/libc/manual/html_mono/libc.html#Numeric-Input-Conversions>
ISO C2x:
<http://www.open-std.org/JTC1/SC22/WG14/www/docs/n2731.pdf#subsubsection.7.21.6.2>
Still, from the documentation linked above, it seems to me that
"%Ln" is supported as a glibc extension, and doesn't fall into
"either no effect or undefined behavior" as says the GCC warning
shown in the bugzilla report. I didn't modify the documentation
regarding %n, and recommend investigating a possible GCC bug.
