Unless you change your mind and create (yet another, we've all done it)
structure based string type, here's a suggestion: have a very clear
convention in the naming as to which of your functions return the
original string, perhaps modified (convert case, trim the
right-hand-end) and which return a new string.  In fact, think hard
about this all over (should replace always create a new string, create a
new string when lengthening but not shortening, or realloc when
necessary?).
