And /etc/profile didn't come with the MSYS installation?  It's a file
you concocted?  If the file comes with the installation, then MSYS are
the ones who need to fix it.

??? You mean MSYS2 Bash doesn't convert the colons to semi-colons (and
the /d/foo/bar file names to Windows d:\foo\bar) when they pass
INFOPATH to native MS-Windows programs?  That's a terrible bug.  Doing
these conversions are the main reason for MSYS existence, and the main
difference between it and Cygwin.

Do they perform these conversion on PATH?

No, the path separator on Windows is _always_ semi-colon.  Emacs and
our docs are right, and MSYS should be fixed.
