Why is this a good change?

It was always using a temporary file; it just used to use a temporary file 
that was a shell script fragment and needed to be read with "eval". It 
can't be done entirely in core because it may be determined before a 
conflict and only used when run with --continue after the user resolves 
the conflict.

Ahh, Ok.

Using a _known_ and defined format, instead of ad-hoc scriptlet, is an
improvement.

I still wonder if we can avoid using three separate "git show" and "git
config" invocations, though.  But a half of that inefficiency will go away
when this is migrated to C, as a single git_config() will grab all three, 
although the writing side is still very inefficient X-<.

I think we can on the reading side: just use "git config --list", or
perhaps "git config --get-regexp <sth>" (where <sth> can be ".*") which
conveniently has SPC as separator, and feed it to appropriate 3 x 'read'.

On the writing side we can simply write in the config file format, we
don't need to use git-config for that.  Although I wonder if there won't
be trouble with shell escaping and quoting rules (eval / sed, which
I guess does shell quoting / shell unquoting).

On getting the information side we can use git-show with custom format
or git-cat-file fed to while-read-case construct.

This way from 3 x 3 = 9 git commands git-rebase--interactive.sh would
use only 2.

That's not what I meant.
