I imagine a lot of .desktop files are affected by multiple words in the Name field, as freedesktop specs allow it, and we normally leave that field alone.
However, if multiple words affect the operation of wbar or other base operations, then we can easily place an underscore between the two words, replacing the space. I will do that for this one and any other scm I see that has multiple words in the Name field.
I think I remember something regarding the Name field in the early scm testing, I will look up on it tonight. But no spaces in fields that are being parsed is always a good idea.
