bash igncr documentation - where?

[Daniel Barclay]

Where is the documentation of the igncr (ignore-CR) option for Cygwin 1.7's
bash?

(There does not appear to be any reference to it in
- the current Cygwin User's Guide (http://cygwin.com/cygwin-ug-net/),
- the current CygWin FAQ (http://cygwin.com/faq.html), or
- in bash man page from CygWin.

(I did find some e-mail about it from several years ago, but haven't
yet found anything that clearly applies to the current version of Cygwin
bash.))

Thanks,
Daniel
