Calling a Filesystem library function with more than a single constant for an option group results in undefined behavior.

It's not clear what counts as "a Filesystem library function" now that the content has moved from the TS to the IS.

I fixed this editorially by dropping the "Filesystem". Only functions within [filesystems] take these types, which seems to properly scope this rule to the relevant functions.

I thought about that, but wondered whether someone would misread it to suggest that passing one of those options to a function template such as make_pair would be undefined if conflicting bits are set.
