Function find_separator

trailer.c:633–649

* If the given line is of the form * " ..." or " ...", return the * location of the separator. Otherwise, return -1. The optional whitespace * is allowed there primarily to allow things like "Bug #43" where is * "Bug" and is "#". * * The separator-starts-line case (in which this function returns 0) is * distinguished from

 * returns -1) because some callers of this function need such a distinction.
