You're right. I was handraulically trying to copy the bashrc
statements into my posting. Foolish me. Humans stopped typing error
free the moment computer editors and word processors became
widespread.

I was starting to much around with the following in my vimrc:

let &shell='c:\cygwin\bin\bash.exe\ --rcfile c:\cygwin\home\'.
$USERNAME.'\.bashrc'

Then I found the *real* source of my problem. There is nothing wrong
with

set shell=c:\cygwin\bin\bash.exe\ -i

The problem is that it was enclosed

if has("win32")
" etc.
endif

I was running on a 64-bit Windows 7. Heh. Heh heh. (I smack my
forehead).

However, your example is still highly educational, for which I thank
you.
