I don't feel strongly either way.

I think we're trying to be tolerant of some inconsistency in
indentation, but the usual rule is that continuation lines within a
parenthesized list are lined up with the first argument (second list
item) on the first line, or if the first line only contains one list
item, then they are all lined up. However, if there's an entry in
.dir-locals.el, then it is considered a special form and is indented two
spaces.

Yes.

It doesn't add quotation marks implicitly, but it does the same thing
that the shell would do if quotation marks were added, namely that the
entire quoted item is passed as a single argument to ./configure.
If they were instead passed as two arguments, as would be done with the
command
./configure liblua_LIBS=-L/gnu/store/.../libs -llua
Then the 'liblua_LIBS' variable would be "-L/gnu/store/.../libs" and
"-llua" would be passed as a separate argument to configure, which
certainly wouldn't do what we want and might raise an error.
