Your commands are failing because you are not accounding for the carriage
returns. as was said, this change was intentionally done for the purpose of
making scripts MORE portable:
And the portability is what we want to keep.

if you want to keep your grep command, you need to remove CR first:
$ printf 'alpha\r\nbeta\r\n' > CRLF.txt
$ tr -d '\r' < CRLF.txt | grep 'a$'
This is the POSIX method to get portability and Cygwin is POSIX for
Windows. Therefore the bits of documentation for MS-DOS and MS-Windows
isn't in affect for Cygwin grep. In other words the following is in
affect but can be misinterpreted because Cygwin runs on MS-Windows but
isn't considered such.
"This option has no effect on platforms other than MS-DOS and
MS-Windows."
