Hi Mathieu:
Making it into a style might be a challenge. Mode grammar/syntax is not
much fun to play with. Look at the definition of parentheses to see if
they are a word or punctuation. Otherwise, you could probably create an
elisp function that calls R to replace a function with its re-formmatted
equivalent. ESS has several functions that work like that. For
example, take a look at ess-ebcdic-to-ascii-search-and-replace which
replaces EBCDIC passages in the buffer with their ASCII equivalents.
You might also be able to use ESS primitives that find the function
definitions and repeatedly replace them (just like you can search and
replace multiple EBCDIC blurbs in one go).
