Yes, that all looks good. When you run brltty, which version does it say it's
running?

One thing I might add, though, is that, for the general case, it'd be better
to do:

   make distclean
   git pull origin
   ./autogen
   ./configure

this matters the most when, for example, configure has been changed. While this
doesn't happen that often, you never know when it will.

Yes, I understood that. So far, I've been unable to make that happen. I edited
a large file with the line numbers showing, and, as I quickly scroled through
it, I heard a bunch of truncated line numbers followed by the final line fully
spoken.

Perhaps others can give this a try.

Yes, I agree with you. That's certainly how it should be working.

I'm using 1.49.2.

And I sure do want to fix whatever the problem is.
