Should accumulate and accumulate_right keep names of the input?

[AshesITR]

I was quite surprised to see that accumulate_right and accumulate do not keep the names of the input list.
For my case it makes perfect sense to do so, because I am aggregating along a hierarchy.

Maybe there should be an argument to accumulate(_right) for keeping the names?
For compatibility it might be like this:

l %<>% accumulate(myfun) -> no names
l %<>% accumulate(myfun, .keep_names = TRUE) -> leaves names(l) untouched

Currently I work around this with
l %<>% {set_names(accumulate(., myfun), names(.)) wich is somewhat clunky.

I could submit a PR with the necessary changes if desired.

A PR would be great!
