"add -p" has an "e"dit option for editing the patch. I don't recall any
way of directly editing the content.

I'm not sure what you mean by "alongside". If you mean "by editing a
temporary file that corresponds to the index file without munging your
worktree file", then you can do:

  FILE=foo.c
  git show :$FILE >$FILE.tmp
  $EDITOR $FILE.tmp
  object=`git hash-object -w $FILE.tmp`
  git update-index --cacheinfo 100644 $object $FILE

And obviously you could make a script for that if you wanted (but at the
very least, you would need quotes to handle files with spaces, and
probably some magic to handle smudge/clean filters and CRLF properly for
the tempfile).
