doc string of dired-do-kill-lines, "killing" lines in Dired

[Drew Adams]

1. The last two sentences seem redundant, to me:
 
 If you use this command with a prefix argument to kill the line
 for a file that is a directory, which you have inserted in the
 Dired buffer as a subdirectory, then it deletes that subdirectory
 from the buffer as well.
 To kill an entire subdirectory (without killing its line in the
 parent directory), go to its directory header line and use this
 command with a prefix argument (the value does not matter).
 
These sentences both seem to be saying only that `C-u k' on a subdir
header line deletes the subdir listing (all files). Just say that
(once).
 

2. Also, the text in that doc string and elsewhere regarding "killing"
lines in Dired should not speak of "killing" (even though this command
is misnamed this way). The kill-ring is not affected in any way,
AFAIK. For example: Emacs manual nodes Subdir Switches and Dired
Updating.
