+ version 1.2
+ 
+ using character expressions such as [ac-z] or [ace-z] seem to lead to
+ broken regexps.  the following two tests for RETest should show the
+ problem:
+ #149
+ [ac-z]+
+ ace
+ YES
+ ace
+ 
+ #150
+ [ace-z]+
+ ace
+ YES
+ ace
+ 
+ the results that i get are:
+ 149. [ac-z]+
+ 
+    Match against: 'ace'
+    Match: YES
+    Paren count: 1
+    Paren 0 : ce
+ 
+

+ 
+ 
+ Register 0 should be = "ace", but is "ce" instead.
+ 
+ 150. [ace-z]+
+ 
+    Match against: 'ace'
+    Match: YES
+    Paren count: 1
+    Paren 0 : a
+ 
+ 
+ *******************************************************
+ *********************  FAILURE!  **********************
+ *******************************************************
+ 
+ 
+ Register 0 should be = "ace", but is "a" instead.
+ 
+ it would seem that the range is somehow invalidating the previous simple
+ character.
+ 
+ on a related note, the only way to match '-' in a character class is to 
+ escape it and add it at the end.  that seems wrong.
