^[n..m] selector ranges insert undesired spaces

[cspotcode]

Given this stylus:

.s1
  &-s2
    &-s3
      &-s4
        ^[2]
          // first three levels of selectors
          syntax: "^[2]"
        ^[0..2]
          // I expect this to be identical to the above, but it's not
          syntax: "^[0..2]"

I get this output:

.s1-s2-s3 {
  syntax: "^[2]";
}
.s1 -s2 -s3 {
  syntax: "^[0..2]";
}

In #1240 one of the examples uses ranges to insert into the middle of a selector:

.foo
  & .bar
    width: 10px

    ^[0]:hover ^[1..-1]
      width: 20px

However, that example breaks when I make a slight adjustment.

// When mouse is over .foo, .bar-baz should become wider
.foo
  .bar
     border: 1px solid grey
     &-baz
       width: 10px
       ^[-2]:hover ^[-2..-1]
         width: 20px

.foo .bar {
  border: 1px solid #808080;
}
.foo .bar-baz {
  width: 10px;
}
.foo:hover .bar -baz { /* <-- wrong selector */
  width: 20px;
}

Thanks for the report. I've fixed this bug in the rc-0.54 branch.
