	* etags.c: (C_entries): In case '}' decrement bracelev before testing it.

2007-11-15  Masatake YAMATO  <jet@gyve.org>

	* etags.c (C_entries): In case '}', set fvdef to fvnone
	unconditioned to (!ignoreindent && lp == newlb.buffer + 1).

2007-11-15  Francesco Potort�<pot@gnu.org>

	* etags.c: (C_entries): Reset the fvdef machine when out of function.
	(C_entries): Parse start of C comment as a space == end of token.
	This is not necessary for C++ comment, already parsed as newline.
