Edge-cases that stick out to me involve non-digit text after the
colon such as "C:\path\to\file.txt",
"resident_evil:afterlife.mov" or "rockets:321blastoff.swf" This
could be remedied by tightening the regexps:

let file=matchstr(a:arg,'^.*\ze:\d\+$')
let line=matchstr(a:arg,'^.*:\zs\d\+')

And there are failure conditions if the filename doesn't contain
a colon, so you might put in a check something like

if file==''
let file=a:arg
endif
if line==''
let line=1
endif

before issuing the :exec call.
