Minor buglet in config.log

[Jeff Squyres]

Greetings Autoconfers.

As far back as I can remember, when you run

    ./configure FOO="bar baz yow" --prefix=/tmp/somewhere

it shows up in the first few lines of config.log as

    $ ./configure FOO=bar baz yow --prefix=/tmp/somewhere

Which means that if you want to cut-n-paste the exact configure string  
that was used to run configure, you have to go manually insert the  
quotes before executing it.

Is there any chance of getting autoconf to quote the full FOO token in  
config.log?  I realize that the shell strips out the quotes by the  
time autoconf gets the argv; autoconf would have to detect that there  
is whitespace in a token and insert quotes manually when writing  
config.log.

This is a minor nit, but it is something that has been around for  
years and is somewhat annoying, for example, if we set CFLAGS to a  
multi-token value when running configure.

Thanks!
