- The following transformations are applied:
- - Space characters are replaced with regular white space characters.
- - Sequences of space characters are truncated to a single space.

- - If a '%' character is encountered, the next character is expected
- to be a single digit index into argv. If it is not a digit or
- outside the bounds set by argc, processing fails. On success,
- the argv value is inserted and processed as described above.
- - A '%' character can be escaped by writing '%%' or, if inside
- a double quite string, by writing \%.
