The question whether one space or two should go at the end of a sentence goes no where. It's a matter of personal preference.
There's no industry standard. I was the executive editor of my law review, and edited pieces from professors, students, and one federal appellate judge. Some used one space; others two. The judge used one space.
Chicago Manual of Style--what we used on the law review--and pretty much anything to which Bryan Garner attaches his name, advocate for one space. For exactly the reason of that the OP mentioned.
I've personally come to use one space between sentences. It's easier, faster, and--in my opinion--looks better. But I also understand that it's best to conform with the style with which you're working. On the law review we used two spaces, but it was only because that's the law review had always done it. In a year I'm going to clerk for a district-court judge; if the judge uses two spaces, then so will I.
This thread reminds me of the new Garner-Scalia book. Garner advocates for the use of contractions in legal writing. Judges Easterbrook, Kozinski, and others frequently use contractions in their writing. Justice Scalia thinks that they look horrible. Again, it's a matter of personal preference.
One thing that I've learned about the law is that at times, you've got to conform to the way things are done. And not fight it.
