I do not think those issues have much relevance under UNIX/Linux. For example, : is the separator character for $PATH, so cannot appear in the name of an entry of $PATH. Likewise, quotes and spaces have no special meaning inside $PATH. (Though they generally do have meaning in surrounding contexts.) Anyways, I think a strong argument could be made that unix and windows should have completely separate code for handling PATH issues. They can share common utilities, but the rules are so very different that sharing code just makes things complicated for little reason.
