Shell meta characters in an argument causes the configure script
to freak out and generate a config.status file that contains
syntax errors.
Bug triggered by ./configure --with-foobar=\''`"$'.
* acgeneral.m4 (AC_INIT_PARSE_ARGS): Quote single quotes that end
up between single quotes. Protect arguments of echo with double
quotes.
(AC_INIT_PREPARE): Likewise.
(AC_PATH_PROG): Protect argument of test.
(AC_OUTPUT): Quote meta characters in ac_configure_args.
