Hi
emacs -Q -D
Insert a line like the following:
otto foo

Place the cursor approximately where the accent is. Type M-- M-\ and
all white space is deleted instead of only the one on the left hand
side.
Neither the Emacs manual nor the delete-horizontal-space's doc string
says anything about how prefix args are handled. But it seems like a
good idea to bind the BACKWARD-ONLY Lisp arg to the interactive prefix
arg:

arg to interactive prefix arg, and update doc string.

The other delete commands are those which delete only whitespace

Could you, please, also make the command symmetric? For example
negative arguments are killing on the left hand side of the point and
positive arguments on the left hand side. The default would remain as
is. (There was recently a request--unrelated to M-\--for such a
feature on gnu.emacs.help, killing white space left or right of the
cursor).
That would be cool.
