  89 +The region files written by GSkyRegions were not readable by ds9 when region
  90 +names were specified. It turned out that region names have to be put in quotes,
  91 +either ", ' or {}. I modified the GSkyRegionCircle::read() and write() methods
  92 +to support this logic, where {} are used in GSkyRegionCircle::write() (#3280).
