fold: don't truncate multibyte characters at the end of the buffer
* src/fold.c (fold_file): Replace invalid characters with the original
byte read. Copy multibyte sequences that may not yet be read to the
start of the buffer before reading more bytes.
* tests/fold/fold-characters.sh: Add a test case.
