This shows why 04/10 should have had the overall plan for these two
steps. We want a short-and-sweet name "diff-flush-patch" to mean
"flush all the queued diff elements" so rename the singleton one
from diff-flush-patch to diff-flush-patch-filepair to make room in
04/10 and then introduce the "diff-flush-patch-all" in 05/10.
I just said with the above explanation the changes in 04/10 and
05/10 become undertandable, which is a bit different from being
justifiable. "diff_flush_raw()", "diff_flush_stat()", etc. are
_all_ about a single filepair. I'd rather see diff_flush_patch()
to be also about a single filepair.
It may be helpful to have a helper that calls diff_flush_patch() for
all filepairs in the queue, but can't that function get a new name
instead? By definition, it will be called much less often than a
pair-wise one, so it can afford to have a longer name.
diff_flush_patch_queue() or something, perhaps? I am not sure if it
should be diff_flush_queue_patch(), or even
diff_flush_queue(struct diff_options *o, diff_flush_fn fn);
where diff_flush_fn is
typedef void (*diff_flush_fn)(struct diff_filepair *p,
struct diff_options *o, void *other_data)
that can be used to flush the queue by calling any of these
filepair-wise flush functions like diff_flush_{raw,stat,checkdiff,patch}.
This last approach might be overkill, but if you want to try it,
you'd need a preparatory step to give an unused "void *other" to
diff_flush_{raw,patch,checkdiff} as diff_flush_stat() is an oddball
that needs an extra "accumulator" pointer. I actually wonder if
that "diffstat" pointer should become part of "struct diff_options",
though. Anyway.
