Substituting grep (and other) output to open files in Vim

[Richard Hartmann <richih.mailinglist@xxxxxxxxx>]

Hi all,

I would like to be able to do the following, but I am stuck. Every
pair of lines is what I would execute and what it would be transferred
to. I am assuming that every file "name" (i.e. including colons etc) I
am running Vim on does not exist. If it exists, it should be opened
instead of magic happening. "foo" exists while "foo:" etc do not.

vim foo:
vim foo

vim foo:bar
vim foo

vim foo:123
vim foo +123

vim foo:123:
vim foo +123

vim foo:123:bar
vim foo +123

Ideally, the same would happen for vimdiff. And yes, vimdiff heeds
only one +n and the last one on the command line wins. That's fine.


I am pretty sure this is trivial to do in zsh, but as I said I am at a
loss as to how..


Thanks,
Richard
