-------------------------------------+--------------------------------------
 The unified python portgroup has this code:
 {{{
 proc python_get_version {} {
     if {[string match py-* [option name]]} {
         return [string range [option subport] 2 3]
     } else {
         return [option python.default_version]
     }
 }
 }}}
 This is strange and produces bizarre dependencies like this:
 {{{
 $ port deps py-urlwatch
 Full Name: py-urlwatch @1.14_0
 Library Dependencies: py-u-futures
 }}}
 In fact py-urlwatch declares a dependency on
 port:py${python.version}-futures. In the stub port, python.version is the
 3rd and 4th characters of the port name (for "py-urlwatch", that's "-u").
 In the non-stub ports, it takes the default version. This seems exactly
 backwards doesn't it? Shouldn't the condition be:
 {{{
 if {![string match py-* [option name]]} {
 }}}
 Or perhaps rather:
 {{{
 if {[string match py\[0-9\]\[0-9\]-* [option name]]} {
 }}}
