Yes. When writing LaTeX, I put line breaks in after phrases and clauses, as well as at every sentence end. I'm following exactly Kernighan's advice from old nroff documentation.
As a result, my text is very ragged right. I don't even notice it because I'm concentrating on meaning, not form.
Or you could just set your line wrap margin pretty low, e.g. 50 or 60 characters, and then when you edit don't re-wrap. Requires less thinking about where to break lines, while still keeping most changes localized to a line and thus cleaner diffs.
In most situations, there should be some sort of semantic break in your sentences every 80 characters or less. (It may not be demarcated with a comma.) If there isn't, you may want to consider reworking those sentences for clarity.
