And anticipate occasional multibyte line wrapping owing to:
> A poorly rendered line may otherwise become wrapped when enough of
> spurious U+FFFD (0xEF 0xBF 0xBD) characters claim more columns than
> are available (75) and then invalidate line correspondence under test.
Observe that for "vim_ex_command.vim" another workaround is
chosen: the long line containing an only multibyte character
near its EOL is conversely made longer by padding and moving
the character to a separate _tail_ part of the wrapped line.
That is, the _head_ part of the line is all ASCII characters
and the wrapped _tail_ part is a mix of various characters
whose total byte count is within bounds.
Other unmodified tracked files of interest:
java_lambda_expressions.java,
java_lambda_expressions_signature.java,
java_numbers.java,
markdown_conceal.markdown,
vim9_generic_function_example_set.vim
Also, remove stray U+FFFC (0xEF 0xBF 0xBC) characters.
