Most git binaries link to gettext's libintl8 /usr/bin/cygintl-8.dll but a number 
of Git shell scripts:

/usr/libexec/git-core/git-bisect
/usr/libexec/git-core/git-filter-branch
/usr/libexec/git-core/git-merge-octopus
/usr/libexec/git-core/git-merge-one-file
/usr/libexec/git-core/git-merge-resolve
/usr/libexec/git-core/git-mergetool
/usr/libexec/git-core/git-quiltimport
/usr/libexec/git-core/git-request-pull
/usr/libexec/git-core/git-submodule
/usr/libexec/git-core/git-web--browse

each source:

	. git-sh-setup in /usr/libexec/git-core/

which sources:

	. "$(git --exec-path)/git-sh-i18n" in /usr/libexec/git-core/

which sources:

	. gettext.sh in /usr/bin/

which defines shell functions which run the gettext binaries:

	/usr/bin/gettext
	/usr/bin/ngettext

so not easily detectable, probably needing cygport REQUIRES=gettext.
