[PATCH 1/2] rebase -i: reword in-editor documentation of "exec"

[Jonathan Nieder <jrnieder@gmail.com>]

The argument to the "exec" insn represents a command to be passed to
the user's shell.  (At first I misread the description as meaning it
should itself be the name of a shell.)

While fixing that, format the description to more closely parallel
the descriptions of other commands.

Before:

 #  e, edit = use commit, but stop for amending
 #  s, squash = use commit, but meld into previous commit
 #  f, fixup = like "squash", but [...]
 #  x <cmd>, exec <cmd> = Run a shell command <cmd>, and stop if it fails
 #
 # If you remove a line here THAT COMMIT WILL BE LOST.
 # However, if you remove everything, the rebase will be aborted.

After:

 [...]
 #  f, fixup = like "squash", but [...]
 #  x, exec = run command using shell, and stop if it fails
 #
 # If you remove a line [...]

It would be nice to say "stop for amending if it fails" (or similar)
to make the relationship to the edit insn clearer, but it is not clear
how to make room for that.
