Yes.  When sentence-end-double-space is nil on current master, this
text from the original report:

xxxxx xx x xxxxxxx xxxx xxxx xxxxxx xxx xxxxxxx xxxxxxxxxx. xxxx xx x
xxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xx x xxxxxxx
xxxxxxxxxxxxxxxx. xxx xxxxxxxxxx xxxxx x xxxxxxxx xxxxxx xxx xxxx
xxx'x xxx xxx xxxx xxxxx xxxxxxxx xxxxx.

Fills to this:

xxxxx xx x xxxxxxx xxxx xxxx xxxxxx xxx xxxxxxx xxxxxxxxxx. xxxx xx x
xxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xx x xxxxxxx xxxxxxxxxxxxxxxx.
xxx xxxxxxxxxx xxxxx x xxxxxxxx xxxxxx xxx xxxx xxx'x xxx xxx xxxx
xxxxx xxxxxxxx xxxxx.

This is what was indicated as expected in the original report.  I'm
therefore closing this bug.

Thanks,
