* Other PR comments.
* #2954: Provide std::conjunction and std::disjunction substitutes
* #2954: Use conjunction and disjunction substitute to make formatter specializations for ranges and maps more robust (especially for Visual Studio compiler family)
* #2954: As workaround for older MSVC compilers split formatter<std::filesystem::path> partial template specialization into two explicit specialization.
* 2954: Add test case
* Provide simplified implementations of conjunction and disjunction
* Remove workaround explicit specializations if the partial specialization would cause an ambiguity error
* Eliminate extra-test and merge it into existing std-test instead. Add conditionals for filesystem::path testing that does not run into the ambiguity problem.
Made enums involved in bitfields unsigned by specifying their underlying type as unsigned char.
Due to a bug, when specifying an underlying type, gcc < 9.3 warns about bitfields not being big enough to hold the enum, even though they are. So keep the plain enum for old gcc.
An example of the bug is here:
https://godbolt.org/z/58aEv8zEq
Created FMT_UNCHECKED_TYPE that resolves to special identifier _Unchecked_type for Microsoft, but to a dummy string otherwise. Using
_Unchecked_type is invalid because underscore + uppercase is a reserved identifier.
