[PATCH] sh-18n: quell "unused variable" warning

[Michael J Gruber <git@drmicha.warpmail.net>]

    CC sh-i18n--envsubst.o
sh-i18n--envsubst.c: In Funktion »main«:
sh-i18n--envsubst.c:71:22: Warnung: Variable »show_variables« gesetzt,
aber nicht verwendet [-Wunused-but-set-variable]

show_variables is indeed unused. Comment it out rather than remove it so
that the relation with upstream remains clear.

Why is it that even with LANG=C exported, gcc gives localized warnings?

And yes, I'm on gcc 4.6 now (F15)...
