Okay.

Do you need to use that instead of MSYS's own 'sed'?

The command line resembles a path, so MSYS translates it,
even though the translation is more aggressive than you
want in this case.

You can avoid the problem by using MSYS's own 'sed', which
understands the MSYS filesystem and doesn't need any
translation:

  $echo a=a | sed s/=//
  aa

If you use a non-MSYS 'sed', then you'll get this problem:

  $echo a=a | /c/usr/bin/sed s/=//
  c:\usr\bin\sed.exe: -e expression #1, char 4: Unterminated `s' command

but it's generally possible to work around it by writing
the command so that it looks less like a path, e.g.:

  $echo a=a | /c/usr/bin/sed -e';s/=//'
  aa
