*	SI-8525 Clarify usage of -Xlint:_,flag	Som Snytt	2014-07-16	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Also clarify usage of -Xlint flag. Align more with javac -Xlint:all,-flag,flag where once a flag is explicitly enabled it cannot be disabled, but where the wildcard is a backstop only. (There is no all option yet here.) -Xlint and -Xlint:_ just set a flag which is consulted by any unset lint warning. Xlint warnings consult the state of Xlint when they are unset. Individual -Ywarn-ings do not. Other warnings are explicitly set to false. They can only be enabled programmatically. Some tests are corrected. Also, option order is no longer significant, see the unit test.
*	SI-8610 -Xlint is multichoice option	Som Snytt	2014-07-08	1	-0/+1
	Make -Xlint a "multichoice" option for purposes of option parsing. This allows turning on "lint with these warnings" instead of only "turn off these warnings but enable other lint warnings". ``` $ scalac -Xlint:warn-adapted-args linty.scala # lint plus a warning $ scalac -Xlint warn-adapted-args linty.scala # same $ scalac -Xlint linty.scala # same as now $ scalac -Xlint -- linty.scala # ok, not necessary $ scalac -Xlint _ -- linty.scala # another funky underscore ``` This would also enable Xlint options that are not standalone options, although that is not implemented in this commit. For example, `-Xlint:no-missing-interpolator` could be used to disable that warning. (There is no `-Xoption:flavor=off` syntax.) (`no-` switches would not be enabled by `_`.)
