bash bobbles CR-LF

According to Doug McIlroy on 2/22/2008 12:14 PM:
| Most cygwin utilities gracefully handle text files with lines
| terminated by either a bare newline or carriage return-linefeed.
| Not so with bash (version 3.2.33(18)-release (i686-pc-cygwin)).
| There are various symptoms, but the clearest is that, in
| a script with CR-LF terminations, an empty line draws the
| diagnostic, "$'\r': command not found".

And this is intentional, since by default, cygwin emulates Linux, and bash
on Linux doesn't ignore CR.  Reread the announcement (and consider using
d2u or enabling the shell option igncr to overcome the default).
