doh, never mind that reason; typo/brain-damage.
I think it's useful to be able to know if an API is going to modify the
input parameters at all. for example, without const, you don't know --
outside of reading the code, or perhaps the documentation -- if this will
segfault or not
genxAddText(w, "asdfasdfasdf");
Now, that's unlikely, but the add bounded text might try to cheat and
temporarily insert a \0 byte and then replace it. If the compiler puts
fixed text strings into read-only memory, as it is free to do, then such
a technique would probably segfault.
