Even when you had a GVIM server running? What was the error? Is this
from bash or something else?

Is this trying to dump stdin via Ex mode? My <C-o> and <CR> assume a
call from insert mode, what did your trailing <C-u> do?

I get a buffer named "-" and a buffer named "file\")"! Can't seem to
figure out a way around, I wonder if this is a shell limitation?

Right, I forgot. It's too late for me, dunno how to solve this.

Actually, the writable check is a different block just below the code
above, it didn't change. There are three in file_open():
1. Verify not directory
2. Verify exists, prompt to create if not (above)
3. Verify not read-only
You're now seeing the third, not sure why unless it is already opened
by another server?

Arguments and wrappers and global variables, oh my! With too little
sleep, I can't even get my head around this to imagine.
