Most platforms can get by perfectly well with the default command line size,
but some platforms need more. This patch allows the command line size to
be configured for those platforms that need it. The default remains 256
characters.

How big of a command line do you need?  For no scientific reason other
than there not being any obvious need for a larger size MIPS is using 256
and I think unless you're asking for a huge number it will be better to
just raise that constant.

The answer depends on the platform, but it's at 438 characters on a typical
platform. If I *had* to pick a number, I'd probably go for 512 characters; I
just hate to force others to use memory they aren't going to use.


I wonder if the memory could be dynamically allocated. It would of course be a much larger patch.
