I think this is related to the ssh_askpass problem mentioned in Issue 166 and 
it has also popped up on the 
vim_mac mailing list a couple of times.  It seems to be some sort of linking 
problem but I'm not sure what to do 
about it.  Any help/patches would be welcome.

I know what causes this now.  When ssh needs a password it will ask for one.  
If you're running vim in terminal mode it just prompts on the terminal, which 
always works.  If you're in the GUI ssh will try to use the ssh_askpass program 
which unfortunately doesn't exist on Mac OS X.

Here is a temporary workaround:

* download the attached file (macos-askpass) and put it somewhere in your path
* make it executable (chmod a+x macos-askpass)
* invoke MacVim from the terminal like this (the DISPLAY is not needed if it is 
already set)

    SSH_ASKPASS="macos-askpass" DISPLAY=":0" mvim

* you can now :e scp://user@server/

This is a kludge.  I will try to come up with a nicer permanent solution (i.e. 
bundle some askpass program with MacVim and set the environment vars 
automatically).

However, do note that ssh will ask for a password _every time_ you change 
folder, open a file, write a file, whatever.  This quickly gets tedious.  A 
better solution is to set up a private/public key.
