Traditionally we had 16kB limit when formatting log messages for output, because it was easier to arrange for the caller to have a reasonably big buffer and pass it down without ever worrying about reallocating. This changes the calling convention of pretty_print_commit() to lift this limit. Instead of the buffer and remaining length, it now takes a pointer to the pointer that points at the allocated buffer, and another pointer to the location that stores the allocated length, and reallocates the buffer as necessary. To support the user format, the error return of interpolate() needed to be changed. It used to return a bool telling "Ok the result fits", or "Sorry, I had to truncate it". Now it returns 0 on success, and returns the size of the buffer it wants in order to fit the whole result. Signed-off-by: Junio C Hamano <gitster@pobox.com>
