Version 024 is out.

I fixed an embarrassing bug in yyerror and yyerrorf. The problem is that all of the current test cases use correct queries; the handling of syntax errors is not exercised. The test has a coverage which is too poor to be useful for the discovery of regressions in the face of broadly sweeping changes throughout the code base.

Also, a @(collect) and @(coll) bug that was introduced in txr-015 is now fixed. What was happening is that whenever a collect didn't yield any bindings (even if its body otherwise matched something one or more times!) it would generate a match failure.
