I though about that too, but preferred not to cause too much noise so that I'd
get your attention :)

Something similar to what I did in lintian to handle quotes for the diversions
check needs to be used.

Blame lintian for that, I didn't think twice before replacing "my"
with "our" :-/

By the way, I noticed the duplication of that line about fifteen lines below,

Of course, you got what I meant ;)
By the way, as I type there's another archive wide run processing all of i386
