The reason would become clear once you think what string you are
feeding eval_gettext with if you do not escape.  The translators
translate a fixed string (possibly with placeholders) to a fixed
translated string (possibly with placeholders).

	eval_gettext "Stray $dotest directory found. ..."

would allow the shell to expand $dotest before eval_gettext sees it,
which would mean the string is no longer a constant.
