[ESS] Jumping to (or listing) functions in a given file?

[Steve Lianoglou]

Nice!

The imenu/ido works *almost* perfect.

Say I have these two S4 defs:

setMethod("something", c(x="character"),
function(x, ...) {
})

setMethod("something", c(x="integer"),
function(x, ...) {
})

Using Imenu in an emacs gui, "something" is repeated twice, w/o the
ability to distinguish the "character" version vs the "integer"
version.

Using imenu/ido from the terminal, "something" is only listed once.

Changing the regex used in ess-5.11::ess-menu.el from
    ("Methods" "^.*set\\(Group\\|Replace\\)?Method(\"\\(.+\\)\"," 2)
to
    ("Methods" "^.*set\\(Group\\|Replace\\)?Method(\"\\(.+\\)\",?" 2)

Now includes
something", c(x="integer
something", c(x"character

which seems to work better in both the GUI and when using this via
terminal + Imenu stuff you pointed to.

Although I reckon an even better regex could be jimmied up (to include
all params beings S4-dispatched against?), perhaps this might be a
good enhancement in base ess for now?

Thanks for the Imenu tip, using it w/ ido is awesome.
