New description:

 We've apparently run into this in a few places before: The code in
 control.c that extracts the command from the command line will discard the
 rest of the line too, if the line is empty.

 This means that the control.c code can't distinguish these cases:
 {{{
 +FOO A
 B
 C
 .
 }}}
 and
 {{{
 +FOO
 A
 B
 C
 }}}
