Just to note, the proposals so far don't prevent a "smart-ass" function from
freeing the buffer when it's called underneath the use/release scope, as in:
with_commit_buffer(commit); {
fn1_needing_buffer(commit);
walk_rev_tree_or_something();
fn2_needing_buffer(commit);
} done_with_commit_buffer(commit);
walk_rev_tree_or_something() might need to read commits to do its thing, and it
could still choose to free their buffers (as in rev-list.c finish_commit()). If
those commits includes the one being "retained", the call to fn2 will still see
NULL despite it being in a 'protected scope'.
Are the objections to using a reference count?
