Comment (by Algunenano):

 A similar thing happens in the functions that output from a stringbuffer
 (ST_AsText, ST_AsKML...): the string is generated in the stringbuffer,
 copied for output and then copied again in `cstring_to_text` (which also
 calls strlen on the whole string, even though we already know its size).
