[PATCH] gcc/doc: Clarify warning for variable unused

[Nathan Myers]

[Guessing this should be in the 16.x branch too.]

In the www gcc-16/porting_to, two lines in comment text on
the example code for -Wunused-variable was changed from
"pre/postincrement used" to "pre/postincrement result used".
Approval there directs that the change should be propagated
back to the texi source the example came from. This is that
propagation.

gcc/Changelog:
	* doc/invoke.texi: insert "result" in comment text
