Yes. All of them. All four.
The advantage to the first approach is that authors of future string
mutators won't have to remember to handle this case specially, and I
have very little confidence that they would.
I'll look into this.
Either way. The advantage of quitting a string transformation function
early when the length to modify is zero is you save more overhead than
just calling scm_i_string_start_writing. But it's your call. Whatever.
