top: needed 'Ctrl' bottom window fixes were discovered <=== port of newlib da36ff2b

Browse Source 
______________________________ original newlib message

As it turns out, some of the 'environ' strings are big
enough to overrun the initial buffer sizes. And, while
no real harm was done (other than to silently truncate
the output), this patch will increase the buffer size.

While we're at it. we will normalize a few more buffer
declarations along with correcting a couple typos too.
