+ * variable.h (kpathsea_var_expand): returns string "$FOO" if FOO
+ is not defined, not the empty string; whereas ${FOO} does return
+ the empty string. Maybe not the ideal interface, but seems
+ undesirable to change now.
+ * doc/kpathsea.texi (Programming with config files),
+ (Auxiliary tasks): document this.
+ Noted by Andreas Scherer, r49726.
