I'll jump in: That does not appear to be Cygwin nano, but some other, Windows-based
nano, which would expect Windows type paths, not Cygwin type paths.  You have (at
least) two options:

- Drop that nano and install the Cygwin one;
- Invoke that nano with a Windows path, perhaps like this:

nano $(cygpath -wa ~/.bashrc)

Personally, I'd go with the first option, since CYgwin nano is more likely to
play nicely with Cygwin files ...
