The more I read about this the more I think that we should just go
ahead and allow all zle widget functions to get (an arbitrary number
of) arguments (strings). If no arguments are given, the function uses
its defaults. We could than probably have a couple of generic
functions (e.g. for word movement) and define aliases to them with
fixed arguments (as Peter suggested with flags), probably even for
some of the functions that are currently real builtin widgets.

I mean, we were talking about allowing arguments for the search-
functions anyway, so why not use it it many more places.
