Yes, a cheap shot, but I think one trying to make a point.

Mhh.. I guess I didn't realize how strongly git still is "many
commands that are good at what they do" that together form a coherent
entity.

Very good point, perhaps we should consider double-checking them all
and improving them for one of the next 1.x releases.

The patch looks like a step in the right direction, but if there is
interest in improving the error messaging system why not do it right
and make it generic. Instead of each file reinventing the wheel create
a more generic system that uses a configuration file (I think this was
suggested earlier). If we choose something like that, perhaps it would
be nice to add a 'scripting' mode, which provides with a CLI-like
messages instead of the usual human-readable ones (and thus less easy
to parse).
