+2013-01-25 Alan Mackenzie <acm@muc.de>
+
+ Fix a bug in the state cache mechanism. Refactor this a bit.
+
+ * progmodes/cc-engine.el (c-parse-state-get-strategy): Remove the
+ `cache-pos' element from the return value.
+ (c-append-lower-brace-pair-to-state-cache): "Narrow" to end of
+ buffer to enable proper searching from beyond HERE. Amend the
+ test for detecting the sought brace pair. Amend the value written
+ to the "brace desert cache" when the brace isn't found.
+ (c-remove-stale-state-cache): Rename `good-pos' to `start-point',
+ and several other variables analogously.
+ (c-remove-stale-state-cache-backwards): Change `cache-pos' from a
+ parameter to a locally calculated variable.
+ (c-parse-state-1): Change the calling conventions to the two
+ defuns involving `cache-pos'.
