Subject: [PATCH] quotearg: don't attempt to store 1 << 31 into an "int"
* lib/quotearg.c (quotearg_buffer_restyled): Building coreutils
with gcc's new -fsanitize=undefined and running its tests triggered
some new test failures, all with this diagnostic:
lib/quotearg.c:629:62: runtime error: left shift of 1 by 31 places \
cannot be represented in type int
Use "1U << ..." in place of "1 << ...".
