Bug#342938: debbugs: block by command not documented

[Ken Bloom <kbloom@gmail.com>]

Package: debbugs
Severity: minor


Looking through the bug logs for #342892 and #342879, I noticed the
use of the block by command to control@b.d.o, and I didn't understand
what it does. I tried checking the documentation, but it's not
documented on b.d.o.
