When running "add -e", if launching the editor fails, we do
not notice and continue as if the output is what the user
asked for. The likely case is that the editor did not touch
the contents at all, and we end up adding everything.

Trying to be lazy and comparing files with fake-editor.sh to avoid
having to provide another example text does not work well: the blob
name changes when SHELL_PATH changes, and so does the 'index' line
in the diff.
Therefore provide a second example text.
Noticed by Mike Ralphson.

With "git add -e [<files>]", Git will fire up an editor with the current
diff relative to the index (i.e. what you would get with "git diff
[<files>]").
Now you can edit the patch as much as you like, including adding/removing
lines, editing the text, whatever. Make sure, though, that the first
character of the hunk lines is still a space, a plus or a minus.
After you closed the editor, Git will adjust the line counts of the hunks
if necessary, thanks to the --recount option of apply, and commit the
patch. Except if you deleted everything, in which case nothing happens
(for obvious reasons).
