But what about dialogue?

I've just learned that a particular formatting quirk that drives me up the ever-lovin' wall is, in fact, the proper way to format the item in question. (That would be an ellipsis.)

Now, it makes sense to format it correctly ([word 1]-space-ellipsis-space-[word 2]) when you're omitting things. But, as usual, no one cares about/thinks about/remembers dialogue. That formatting looks just STUPID when it's applied to someone's speech. 

Aduniad was published with the ellipses in Max and Trev's speech reformatted to match the omission standard and it looks (to me) as if MS Word's autoformat feature was allowed to run wild — I hate the automatic clumping of periods, so I always turn it off. (I only use three anyhow!) 

When I put ellipses into a character's dialogue, it's not because they're leaving something out, but rather that they're either scrambling for words, uncertain as to the listener's reaction, or not sure that they can say what needs to be said. 

Examples:

[Omission]

Before: Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.

After: Four score and seven years ago our fathers brought forth … a new nation … dedicated to the proposition that all men are created equal.

[Dialogue]

"Proper" Formatting: "I … This isn't my home. Keldmere … is," he said.

"Improper" Formatting: "I… This isn't my home. Keldmere…is," he said.

See? The speaker isn't leaving anything out, he's merely a little staggered by the implications of his admission and his words are therefore not flowing easily. I may write away to the publisher whose guidelines sparked this little journey of discovery to ask about dialogue, but I don't know. The same guidelines also seem, in an effort to prevent everything they’re sent from reading like bad fanfic, to be in favor of ambiguous pronouns and/or using one character’s name two or more times in the same sentence.
