whitespace should be normalized in variant descriptions before being shown

[ryandesign (Ryan Carsten Schmidt)]

If I define a variant description like this:

variant foo description {foodesc} {
    ...
}

then the description shows up properly in "port variants <portname>". However if I define it this way:

variant foo description { foodesc } {
    ...
}

then the extra whitespace before and after the description is actually shown by "port variants <portname>".

Also, if I use multiple spaces next to one another, or continue a description onto the next line, like this

variant foo description { here  is    a \
                          long description } {
    ...
}

then these extra spaces are output verbatim in the "port variants <portname>" command. This is in contrast with the port's long description, where port seems to strip leading and trailing whitespace and normalize runs of more than one whitespace character to a single space.

This ticket is for the request to change "port variants <portname>" so that it, too, normalizes whitespace in the variant description, just like "port info <portname>" already does for the port's long description. If the request in this ticket is implemented, then #14031 isn't needed and should be closed as "wontfix".

I implemented this in r33289. Please test!

Wow, I didn't realize it would be that easy. Thanks! Works great as far as I can tell.
