git-sh-i18n.sh: add no-op gettext() and eval_gettext() wrappers

Add a no-op wrapper library for Git's shell scripts. To split up the
gettext series I'm first submitting patches to gettextize the source
tree before I add any of the Makefile and Shell library changes needed
to actually use them.

+==============
+
+NAME
+----
+git-sh-i18n - Git's i18n setup code for shell scripts
+
+SYNOPSIS
+--------
+'. "$(git --exec-path)/git-sh-i18n"'
+
+DESCRIPTION
+-----------
+
+This is not a command the end user would want to run.  Ever.
+This documentation is meant for people who are studying the
+Porcelain-ish scripts and/or are writing new ones.
+
+The 'git sh-i18n scriptlet is designed to be sourced (using
+`.`) by Git's porcelain programs implemented in shell
+script. It provides wrappers for the GNU `gettext` and
+`eval_gettext` functions accessible through the `gettext.sh`
+script, and provides pass-through fallbacks on systems
+without GNU gettext.
+
+FUNCTIONS
+---------
+
+gettext::
+       Currently a dummy fall-through function implemented as a wrapper
+       around `printf(1)`. Will be replaced by a real gettext
+       implementation in a later version.
+
+eval_gettext::
+       Currently a dummy fall-through function implemented as a wrapper
+       around `printf(1)` with variables expanded by the
+       linkgit:git-sh-i18n--envsubst[1] helper. Will be replaced by a
+       real gettext implementation in a later version.
+
+GIT

+Part of the linkgit:git[1] suite
