* configure.in: Cite the variable ac_cv_lib_readline_main, not

ac_cv_lib_readline_readline; the latter isn't set any more, since
we look for 'main' in libreadline now.  Add quotes around
reference to the variable references, too, so this will work even
when a variable's value is the empty string.
* configure: Regenerated.
