Newlines in non-literal tag list in AC_CONFIG_FOO

The manual discourages non-literals in AC_CONFIG_FOO, but does not
forbid them.  There are a few things that break when a variable is used
instead of literal tags (eg. "./config.status TAG" does not work), but
since ce429ecd ("Proper config.status --file/--header and $srcdir
escaping.") newlines in the value of the variable do not work at all:

$ cat configure.ac
$ ./configure
configure: creating ./config.status
./config.status: line 579: foo: command not found
config.status: creating Makefile

The docs say that the tag list can be blank or newline separated, not
distinguishing between literals and non-literals.
