Ok, this was nastier than expected, just because the dependencies between
the different log-printing stuff were absolutely _everywhere_, but here's
a patch that does exactly that.
The patch is not very easy to read, and the "--patch-with-stat" thing is
still broken (it does not call the "show_log()" thing properly for
merges). That's not a new bug. In the new world order it _should_ do
something like
if (rev->logopt)
show_log(rev, rev->logopt, "---\n");
but it doesn't. I haven't looked at the --with-stat logic, so I left it
alone.
That said, this patch removes more lines than it adds, and in particular,
the "cmd_log_wc()" loop is now a very clean:
while ((commit = get_revision(rev)) != NULL) {
log_tree_commit(rev, commit);
free(commit->buffer);
commit->buffer = NULL;
}
so it doesn't get much prettier than this. All the complexity is entirely
hidden in log-tree.c, and any code that needs to flush the log literally
just needs to do the "if (rev->logopt) show_log(...)" incantation.
I had to make the combined_diff() logic take a "struct rev_info" instead
of just a "struct diff_options", but that part is pretty clean.
This does change "git whatchanged" from using "diff-tree" as the commit
descriptor to "commit", and I changed one of the tests to reflect that new
reality. Otherwise everything still passes, and my other tests look fine
too.
