There are quite a few existing codepaths that change their behaviour
based on NULL-ness of ctx.rev field. How would we make sure that
this change have no unintended consequence, I wonder?

Let's update the style of this hunk here like so:
if (!c->pretty_ctx->rev || !c->pretty_ctx->rev->sources)
return 0;
slot = ...;
if (!(slot && *slot))
return 0;
strbuf_addstr(...);
return 1;
I wonder if it is even better to apply de-Morgan to one of the above
two, i.e.
if (!(c->pretty_ctx->rev && c->pretty_ctx->rev->sources))
return 0;
Anyway, thanks. Will queue.
