Though it's a bit of a horrible abuse, you can do

if v:shell_error > 0 | exec v:shell_error | endif

which exploits the fact that an ex command of just a number means
to go to that line. Granted, the range of exit codes may limit
you to a pretty small range (1-127, IIRC), so you can't jump to a
line beyond this max. But it's what you asked for :)

There's no good help target that I could find for the ":<number>"
syntax -- the closest I could get are:

:help gg " the item after it is ":[range]" with no tag
:help cmdline.txt " search for "goto line 3"
:help cpo-- " has a mention of using it
:help 'sol' " has a mention of using it

Hope this helps,
