RTS options parser silently accepts invalid flags
RTS options that do not take arguments (such as -T) silently ignore anything that comes afterwards. For example, +RTS -T,-s or +RTS -T-s turns on collection of GC statistics (-T) but does not print out a summary (-s). Instead, this should produce an error message. Otherwise, users may mistakenly think that options have been applied.
(This has just bitten us in a production system.)
