It would be nice if the --pretty format placeholders had a "shell-quote"
modifier, and we could just do:

  git show --format='GIT_AUTHOR_NAME=%(an:shell)'

or something similar. for-each-ref knows about shell-quoting, but we
can't use it here, because we are looking at arbitrary commits, not just
ones pointed to by refs.

Perhaps by using %an etc., line numbers and --sq-quote:

  $ git rev-list --no-walk --date=raw --format="%an%n%ae%n%ad" --encoding=UTF-8 HEAD |
    while read -r s; do git rev-parse --sq-quote "$s"; done |
    sed -n -e '2s/^ /GIT_AUTHOR_NAME=/p' -e '3s/^ /GIT_AUTHOR_EMAIL=/p' -e '4s/^ /GIT_AUTHOR_DATE=/p'
  GIT_AUTHOR_NAME='Thom'\''as Ràst'
  GIT_AUTHOR_EMAIL='trast@inf.ethz.ch'
  GIT_AUTHOR_DATE='1330935546 +0100'

Yeah, that works. It's a little harder to read than would be ideal, but
should produce the right results (I was initially hesitant to use "read"
because I was worried about newlines in the input. But of course, that's
a non-issue since author ident by definition cannot have newlines in
it).

I think this is a good direction regardless of the sed issue. We end up
parsing ident lines like this in a lot of different places, and I would
not be surprised if they do not all behave exactly the same. Eliminating
one such parser in favor of the standard one in pretty.c seems like a
good thing.

PS If you are going to turn that into a real patch, note that your date
   field accidentally drops the "@" specifier that unambiguously marks
   the number as an epoch timestamp.
