Re: [PATCH 3/4] cat-file: add --batch-disk-sizes option

Duy Nguyen [off-list ref] writes:

There's also syntax sharing. I don't think each command should have
its own syntax. f-e-r already has %(objectsize). If we plan to have a
common syntax, perhaps %(disk-size) should be %(objectsize:disk) or
something. Adding formatting to cat-file --batch from scratch could be
another big chunk of code (that also comes with bugs, usually) and may
or may not be compatible with the common syntax because of some
oversight. --batch-cols=... or --batch-disk-size would be simpler, but
we might never be able to remove that code.

True, but cat-file being a low-level plumbing, I actually am not all
that convinced that it should even know the custom formatting.
Configurability and customizability may look always good, but that
is true only until one realizes that they come with associated cost.
