Version 0.1.7 2013-10-10
- bugfix: invalid comparison results for different-length strings
  es_strcmp, es_strcasecmp, es_strbufcmp, and es_strcasebufcmp
  returned incorrect results if the first string was smaller than
  the second. In that case, the first string was always assumed
  to be lexially lower than the second. If the second string was
  larger than the first, the same issue occured. This did not affect
  equal comparisons, but LT/GT checks lead to invalid result, with
  potentially harsh consequences (e.g. qsort() did not work properly).
  This bug is present for a very long time, potentially down to the
  initial implementation of libestr.
