Hi!

While working on the “reproducible builds” effort [1], we have noticed
that ifrench-gut uses sed on a file where its behavior depends on the
locale.

Examples:
$ sed -e 's/^SET.*/SET ISO8859-15/;s/^TRY.*/TRY
aeio������sinrtlcdugmphbyfvkw�������/' fr-pre.aff > fr.aff
$ LANG=C grep -a TRY fr-pre.aff
TRY aeio����sinrtlcdugmphbyfvkw
$ LANG=C grep -a TRY fr.aff
TRY aeio������sinrtlcdugmphbyfvkw�����������sinrtlcdugmphbyfvkw

$ LC_ALL=C sed -e 's/^SET.*/SET ISO8859-15/;s/^TRY.*/TRY
aeio������sinrtlcdugmphbyfvkw�������/' fr-pre.aff > fr.aff
$ LANG=C grep -a TRY fr-pre.aff
TRY aeio����sinrtlcdugmphbyfvkw
$ LANG=C grep -a TRY fr.aff
TRY aeio������sinrtlcdugmphbyfvkw�������

The attached patch sets LC_ALL so sed will has the same behavior on all
systems.
