Indentation of method call without parenthesis seems wrong

[davidtaylorhq]

# Before
expect("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx").to eq("yyyyyyy"), "zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz"

# After
expect("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx").to eq("yyyyyyy"),
"zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz"

The lack of indentation on the second line makes this quite hard to read.

Curiously, if .to is replaced with some other two-letter method name, then the second line is indented by 5 spaces. (Is .to special-cased somehow?). This works out better, but 5 spaces seems a little arbitrary:

# before
expect("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx").tp eq("yyyyyyy"), "zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz"

#after
expect("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx").tp eq("yyyyyyy"),
     "zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz"

Adding parenthesis to the method call makes things much cleaner:

# Before
expect("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx").to(eq("yyyyyyy"), "zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz")

expect("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx").to(
  eq("yyyyyyy"),
  "zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz",
)

Perhaps syntax_tree should always add parenthesis when method arguments need to be wrapped across multiple lines?
