By ghalliday:

It is normally best to use a StringAttr in a class/struct rather than a StringBuffer. It is smaller, and can represent NULL as well as an empty string.

If this was changed you could then get rid of the special casing of "/" and set the value to "" instead. There would need to be several other associated changes - since it can now be NULL.
