[PATCH v2 0/5] gettext: add gettextln, eval_gettextln to encode common idiom

[Jon Seymour <jon.seymour@gmail.com>]

Currently, if you want to use gettext or eval_gettext to format a message
you may have to add a separate echo statement and a surrounding subshell
in order to interpolate the required trailing new line.

This patch introduces two new helper functions, gettextln and eval_gettextln
which append a trailing newline to the gettext output.

This allows constructions of the form:

	if test -s "$GIT_DIR/BISECT_START"
	then
		(
			gettext "You need to give me at least one good and one bad revisions.
(You can use \"git bisect bad\" and \"git bisect good\" for that.)" &&
			echo
		) >&2
	else
	...

to be expressed more concisely as:

	if test -s "$GIT_DIR/BISECT_START"
	then
		gettextln "You need to give me at least one good and one bad revisions.
(You can use \"git bisect bad\" and \"git bisect good\" for that.)" >&2
	else
	...

Applies cleanly to master and pu.

Revisions
=========
v2: 
	Split modifications to git-sh-i18n.sh into separate commit.
	Extended application to:
		 git-am.sh
		 git-pull.sh
		 git-stash.sh
		 git-submodule.sh
	Removed application to git-bisect.sh, pending stabilisation of this series and js/bisect-no-checkout in next or master.
	
v1: Initial RFC. Included example of application to git-bisect.sh.

Future
======
	Apply to git-bisect.sh
