Yes, which is why I made the post just in case any veteran devs
have issues (pardon the pun) with doing anything. I have 'hacked'
up a patch, but since I'm still learning the ropes here, I figured
it would be a good idea to hold it off and make sure no one
objects to having a short cut for --ignore-externals.

True, and I definitely understand the hesitation with assigning a
shortcut.

That's another good option. i.e. -ie? Sure it is less than the
current length, but it also complicates matters since short cuts
(as far as I know) are one letter. Introducing a 2-letter string
into the mix might break the option structure. (I think it does
break this.)

I don't have much of any involvement in this issue since I don't
use --ignore-externals. I guess my enthusiasm for doing 'easy'
fixes overcame my wisdom in choosing the right issues. Reading
your comments and Blair's, I think the Issue-poster should
really have discussed it here. But I guess this is the same
thing, it's just that I was the one who started it and not
him. :)
