That might be caused by entab, actually. I think there are two cases
here:

* six-space indented line
* two spaces in text that happen to land on a tab stop

entab doesn't distinguish them, but it certainly could. In fact, it
already has an option for that:

-s Minimum spaces needed to replace with a tab (default = 2).

Should we be using entab -s 3? That would make a six-space indent be a
tab and two spaces, but it would certainly handle the period-space-space
case. I actually don't remember people complaining about this.
