[ESS-bugs] ess-function-pattern not working for some valid functions

[Toby Dylan Hocking]

Dear ESS developers,

First of all, thank you very much for ESS, a great piece of free
software which I use every day!

I like using the C-c C-f key sequence to load individual functions
into an inferior R process, but I noticed that it doesn't work for
some syntactically-valid functions, such as

comments.and.ex <- structure(function
### some docs
### more
(arg,
 arg2
 ){
  foo
### value
},ex=function(){
  some.code
})

To solve this problem, I propose a patch to ess-mode.el, which simply
updates the regular expression used to match functions.

I have attached the patch and some R code that illustrates several
example functions which are valid R code, but are not currently
matched by ess-function-pattern.

Does this patch pose any problem for you guys? Can you incorporate it
into the main ESS source code?

Thanks for the great package, and for your consideration,
