![]() The xdiff library always emits hunk header lines to our callbacks as formatted strings like "@@ -a,b +c,d @@\n". This is convenient if we're going to output a diff, but less so if we actually need to compute using those numbers, which requires re-parsing the line. In preparation for moving away from this, let's teach xdiff a new callback function which gets the broken-out hunk information. To help callers that don't want to use this new callback, if it's NULL we'll continue to format the hunk header into a string. Note that this function renames the "outf" callback to "out_line", as well. This isn't strictly necessary, but helps in two ways: 1. Now that there are two callbacks, it's nice to use more descriptive names. 2. Many callers did not zero the emit_callback_data struct, and needed to be modified to set ecb.out_hunk to NULL. By changing the name of the existing struct member, that guarantees that any new callers from in-flight topics will break the build and be examined manually.
