grep with -a (or --text) option does not strip CR from line ends

To reproduce, do in CMD’s command line:
D:\> D:\Programs\cygwin2022\bin\perl -we "print qq(abc\r\n)" |
D:\Programs\cygwin2022\bin\grep -a "abc$"
This does not emit anything (contrary to the man page, which says:
If grep decides the file is a text file, it strips the CR
characters from the original file contents (to make regular
expressions with ^ and $ work correctly).
This section in the manpage is preceded by
By default, under MS-DOS and MS-Windows, grep guesses whether
a file is text or binary as described for the --binary-files option.
which may be interpreted so that this stripping only occurs in the
DOS/Windows versions, which the cygwin version isn't.
If you think this is unclear, as the Linux version behaves the same way,
you should report this upstream.
(The same happens on Win10.)
Hope this helps,

P.S. It seems that the mailing list does not allow attaching the output!
So I retry with a shortened version…
