Before doing compile_re() which needs a parameter to identify

whether we should ignore case, determine the flag by calling
compile_flags() first.  Also, make sure that we obtain an
initialized cmd->u.s buffer before processing further.  We
may want to refine this solution later, but for now, make
the changes in order to unbreak world build after a sed(1)
with rev. 1.29 of compile.c is installed.
