Actually, I never considered making mboxrd a config file knob. But yes, it seems like a good idea. I hadn't considered making it the default, actually. The current `--pretty=email --stdout' is probably "good enough" for many users since the "From "-splitting in mailsplit is strict and legitimate commit messages are unlikely to have splittable "From " lines. > This change does not seem to be something we cannot live without, That double negative confused me :x "This change seems to be something we can live without" Yes, I agree. > and as a step in the direction to move all of us to mboxrd, this > feels somewhat a roundabout step.

I don't know if changing the default+deprecation is necessary, but thanks for suggesting a config knob. > After all, between email and mboxrd, the e-mailed patch format is > not something we choose per-invocation basis, is it?

Agreed. Thanks for the suggestions. ------------8<------------- Subject: [PATCH v2] format-patch: support format.mboxrd with --stdout mboxrd is a more robust output format when used with --stdout and needs more exposure. Introducing this config knob lets users choose the more robust format for all their --stdout uses. Relying on --pretty=mboxrd and including all of pretty-formats.txt in the `git format-patch' documentation would likely be confusing to users. Furthermore, this setting is useful across multiple invocations. So introduce `format.mboxrd' as a boolean configuration knob that changes the default --pretty=email format to --pretty=mboxrd when (and only when) --stdout is in use.
