bug#18969: 25.0.50; byte compiler warnings don't conform to GCS

[Tom Tromey]

I got this warning from the byte compiler:

q.el:2:8:Warning: value returned from (aref v 0) is unused

This doesn't fully conform to the GNU Coding Standards.
>From (info "(standards) Errors")

    If you want to mention the column number, use one of these formats:

         SOURCE-FILE-NAME:LINENO:COLUMN: MESSAGE
         SOURCE-FILE-NAME:LINENO.COLUMN: MESSAGE

The output here is missing a space after the ":".

Also I think the "W" in warning should probably not be capitalized.
I note that GCC doesn't do this.
