You mean, like this?:

  body { text-replace: "a" "b" "a" "c" }
I don't think it's underspecified. The spec says:

  Text replacements are applied sequentially.

That is, the first pair of strings are applied (a->b) and then the
second (a->c). As there are no 'a' characters left after the first
pair, the second pair has no effect.

I suggest this text:

  If the first string in a pair is empty, no substitutions will occur
  for that pair. If the second string in a pair is empty, the effect of
  substitutions is that occurences of the first string are deleted.

 > or when a substitution creates an occurrence of the "from" string.

Again, this rule makes is non-ambigous:

  Text replacements are applied sequentially.

One of the examples following that sentence is:

  body { text-replace: "a" "b" "b" "c" }

So, I think it's covered.

Let me know if you disagree.
