 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".
