I'm surprised this doesn't give an error. Using ":set", spaces are
treated as delimiters between options, so it should give an error
something like "E518: Unknown option -i"

which I would expect to happen here too (you escape the one after
"--rcfile", but not the one after "exe").

There are a couple of options, as you can escape the spaces with "\"
(though using Windows "\" as the path separator may then cause
issues; since Vim understands both, I'd stick to using "/" for
portability). You can also use Vim's ability to use :let do more
complex evaluations which is what I expect you want in this case:

:let &shell='c:\cyg…'.$USERNAME.'/.bashrc'

which you can read about at

:help :let-option

I might use "$HOME" instead of the full-path-with-username-replaced
as that should be more portable.
