From: Bo Yang <redacted> The function rewrite_one is used to rewrite a single parent of the current commit, and is used by rewrite_parents to rewrite all the parents. Decouple the dependence between them by making rewrite_one a callback function that is passed to rewrite_parents. Then export rewrite_parents for reuse by the line history browser. We will use this function in line.c.
Did you mean log-line.c or line-log.c or something?
