etags.c fix by Per Cederqvist

lib-src/ChangeLog

+2007-02-04  Per Cederqvist  <ceder@ingate.com>
+
+	* etags.c: (gperf, in_word_set): changed attribute for Java to
+	(C_JAVA & ~C_PLPL).  The previous change introduced 2004-09-13 was
+	broken, as (C_JAVA & !C_PLPL) always evaluates to 0.  This caused
+	import, package, extends, implements and interface to be treated
+	specially for all kinds of C-style files, not just Java files.
