Function find_commit_multiline_header

builtin/fast-export.c:627–650

* find_commit_multiline_header is similar to find_commit_header, * except that it handles multi-line headers, rather than simply * returning the first line of the header. * * The returned string has had the ' ' line continuation markers * removed, and points to allocated memory that must be free()d (not * to memory within 'msg'). * * If the header is found, then *end is set to point at the

 * msg that immediately follows the header value.
