Fixes <https://savannah.gnu.org/bugs/?63589>.  Thanks to Bjarni Ingi
Gislason for the report.

* ANNOUNCE: Update bug counts.

I also killed some pointless white space, refilled affected lines at 72
columns where convenient and non-disruptive to existing text flow, and
corrected a misspelling of Ralph Corderoy's surname.
