gleam format breaks up function call strangely when close to line length

[rawhat]

Hello! Tagging @giacomocavalieri as discussed in the Discord.

The line is formatted like this:

let assert Ok(new_stream) =
  stream.new(identifier, settings.initial_window_size, handler, conn,
  )

It seems like this should either put the closed paren on the same line, or just break out the arguments into separate lines. The latter is what happens when I make one of the variable names longer.

Thank you!

Oh yes, this is a bug. Thank you

@giacomocavalieri can you help with this one? No rush but your context is best!

Working on it! I have a simpler example that gets formatted badly:

pub fn main() {
  function_call(that, is, super, close, to, the, max, line, limit, of, 80, chars,
  )
}

Since the call is 81 chars long it should actually be formatted as:

pub fn main() {
  function_call(
    that,
    is,
    super,
    close,
    to,
    the,
    max,
    line,
    limit,
    of,
    80,
    chars,
  )
}
