If rebase.autoStash configuration variable is set, there is no way to
override it for "git pull --rebase" from the command line.
Teach "git pull --rebase" the --[no-]autostash command line flag which
overrides the current value of rebase.autoStash, if set. As "git rebase"
understands the --[no-]autostash option, it's just a matter of passing
the option to underlying "git rebase" when "git pull --rebase" is called.

Previous patches: $gname287709
Changes:
* --no-autostash is passed to git-rebase (suggested by Paul)
* Error message changed when "git pull --[no-]autostash" is called.
* If rebase.autoStash is unset and user don't pass --[no-]autostash
flag then nothing is passed to git-rebase (i.e. if rebase.autoStash =
-1),
as it should be left to git-rebase to decide what to do.

+ Before starting rebase, stash local modifications away (see

+ done.

+This option is only valid when '--rebase' is used.

+'--no-autostash' is useful to override the 'rebase.autoStash'

+[NOTE]
+Use with care: the final stash application after a successful
