Cannot edit existing password using vim (or gvim)

[ads]

Thanks for the suggestion.

If I do mkdir /dev/shm/foo, then touch /dev/shm/foo/bar, the file bar gets
written correctly.

Somebody else suggested setting nobackup in vim, and I have tried that (and
nowritebackup too). No difference. I have also removed my .vimrc file and
.vim directory, and no difference.

I'm very puzzled.
