It depends on the program the test suite runs. If it runs an MSYS2 program, such programs behave like Posix: they write Unix-style EOLs and do not strip CR characters on text-mode reads. If the program is a MinGW (a.k.a. native Windows) program, it does strip CR on input and add them on output. The difference is in the C runtime used by each kind of programs: MinGW programs use the Windows runtime, whereas MSYS2 programs use their own (Cygwin-derived) C runtime. Texi2any is a native program for this purpose, but all the support tools (Bash, Diff, Grep, Sed, etc.) are MSYS2 programs. It is true that the main purpose of MSYS2 is to allow building software by running Posix configure and build machinery, but in most cases test suites also use Posix shell and support tools heavily, so MSYS2 is also used to run the test suite.
