PATCH: assorted completion function updates

[Oliver Kiddle <okiddle@xxxxxxxxxxx>]

This adds a new function for dsh. The mosh and nm functions are not
really patches to the existing functions: I've had them in unfinished
form for some time. nm handles options for GNU and Solaris variants
(FreeBSD uses GNU nm). _rsync and _wget is just updates to the list of
options.
