I presume you're deliberately ignoring the fact that most paths come
from variables, not from literals, and many come from user input
(sometimes even unintended user input such as a "*" expanded by the
shell)? It's easy enough to rewrite literals to be unambiguous, but in
order to do so for arbitrary input you need to basically implement
(part of) a URI parser...
