Please say _why_ it's a bad idea, i.e. give an example of how someone might
be screwed by this.

Changesets with `non standard' diff contents are _not_ invalid (unapplyable)
changesets unless you use particular options that make the diff contents
unusable by `patch' (e.g., a non-context, non-unified diff) -- and those
options are uncommonly used; tla could even enforce it with not much problem.

The main time you want to avoid any changeset non-standardness is when doing
a commit, and since it always makes its own changesets, it can just be extra
picky; there's no reason to make `changes' be similarly picky.

Would you like fries with that?
