[PATCH] add emacsclient support to open with file:linum syntax

[Jorge Alberto Garcia <jorge.garcia.gonzalez@gmail.com>]

Hi !

I wrote a little patch to emacsclient,
Could you review it ?, this is my first attempt to contribute :)

Description

With this you can do this from cmdline:
$ emacsclient -q  -c lib-src/emacsclient.c:1593

in addition to have our already trusted way
lib-src/emacsclient -q   +1593 -c lib-src/emacsclient.c


- Why I did it ?
I found myself using tools that provides text location using
filepath:line but couldn't  use it directly by emacsclient.
