Ping?

Hello,

Recently on gcc-help@ one of the users asked whether they need to set
-fvar-tracking-assignments on the command line by hand.  The documentation may
be clearer in that this flag has a useful value by default, like -fvar-tracking
(i.e. GCC's behavior is to take the value of flag_var_tracking, unless there's
an override on the command line).

OK to commit?

I also see that introductory text says that the option list mentions negated
forms when they are supposed to be usually used on the command line, which
means that var-tracking paragraphs should in fact use
-fno-var-tracking[-assignments], because normally users will only need the
negative forms?

	* doc/invoke.texi (-fvar-tracking-assignments): Clarify that VTA is
	enabled by default together with var-tracking.

This is fine.

Jeff
