I am a bit confused by these numbering schemes.  When I look at the
'Select Packages' section of setup, my choices for bash are 3.1-6 or
3.1-8.  I assumed they were shorthand for 3.1.16 and 3.1.18.

I think I panicked slightly at discovering Cygwin bash had been
regressed.  I was thinking of all the supplied scripts so I ran
a test of the ~450 shell scripts and found only a handful with CR
embedded:


     /bin/card
     /bin/fixps
     /bin/flea
     /bin/makempx
     /bin/mktexlsr
     /bin/nfs-server-config
     /etc/postinstall/uw-imap-imapd.sh.don
     /etc/postinstall/xerces-c-devel.sh.done
     /etc/preremove/gv.sh
     /etc/preremove/uw-imap-imapd.sh
     /etc/preremove/X-start-menu-icons.sh.done
     /etc/preremove/xerces-c-devel.sh

I found several of the scripts I wrote had embedded CRs.  I'm an
old Unix hand, so I am really baffled how they got into my scripts.
Plus, I always found vim would display the CRs as ^M.  To my dismay
I now discover the vim silently ignores CR when its part of CR-LF
pair, unlike LF-CR.

So, I have subscribed to cygwin and cygwin-announce. I am hopeful I
will not be surprised again.
