The type of a character literal is 'int' in C, but if the user writes a
character /as/ a literal, we should assume they meant it to be a
character and not a numeric value, and thus offer %c as a correction
rather than %d.
There's a special case for multi-character literals (like 'MooV'), which
have implementation-defined value and usually cannot be printed with %c.
These still use %d as the suggestion.
In C++, the type of a character literal is 'char', and so this problem
doesn't exist.

We tried to account for 'uint8_t' by saying that /typedefs/ of 'char'
should be corrected as %hhd rather than %c, but the condition was wrong.
