[Bug-readline] [patch] Fix underquotation in readline/examples/rlfe/configure.in

[Jan Kratochvil]

Hi Chet,

the mail
        Autoconf macros fixes
        http://gcc.gnu.org/ml/gcc-patches/2009-07/msg01604.html
 = sourceware commit 625678e974da5ac861284f13b8a3e65721a59c97

contains the following patch, I haven't found it posted here and/or in present
in readline-6.2.

I have to admit I do not have any warning reproducible but it is more correct
to quote it.
        Be sure to properly quote both the MACRO-BODY _and_ the MACRO-NAME to
        avoid any problems if the macro happens to have been previously
        defined.


Thanks,
Jan
