The documentation says that these functions skip one input character
per literal (non-pattern) format character. Actually, though, they
skipped one input *byte* per literal *byte*, which could be hugely
confusing if either data or format contained multibyte characters.
To fix, adjust the FormatNode representation and parse_format() so
that multibyte format characters are stored as one FormatNode not
several, and adjust the data-skipping bits to advance by pg_mblen()
not necessarily one byte. There's no user-visible behavior change
on the to_char() side, although the internal representation changes.
