tweaking "configure --help" for autoconf changes View as Markdown

Hi Folks:

There's a minor difference between the output of "configure --help"
between PHP_5_3 and PHP_5_4. The change makes it hard to tell what the
default values are for some options.

The options impacted are those defined in configure.in using
PHP_ARG_WITH. A simple example is --with-layout

Here's the string in configure.in:
Type can be either PHP or GNU [PHP]

Here's the output in PHP_5_2 and PHP_5_3:
Type can be either PHP or GNU [PHP]

But here is the output from PHP_5_4:
Type can be either PHP or GNU PHP

This is an offshoot of the move from autoconf 2.13 to 2.65. I've
attached a patch for 5.4 and trunk to use autoconf "quadragraph"[1]
representations of brackets instead of the brackets themselves.

Can someone please apply this?

Thanks,

--Dan
