Improve indentation of builder type calls.
In builder-type calls, it can be very confusing to just indent
parameters from the start of the line. Instead, indent 4 from the
correct function call.
Before:
aaaaaaaaaaaaaaaaaaa()->aaaaaa(bbbbb)->
aaaaaaaaaaaaaaaaaaa( // break
aaaaaaaaaaaaaa);
aaaaaaaaaaaaaaaaaaaaaaa *
aaaaaaaaa = aaaaaa->
aaaaaaaaaaaa()->
aaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
->
aaaaaaaaaaaaaaaaa();
After:
aaaaaaaaaaaaaaaaaaa()->aaaaaa(bbbbb)->
aaaaaaaaaaaaaaaaaaa( // break
aaaaaaaaaaaaaa);
aaaaaaaaaaaaaaaaaaaaaaa *
aaaaaaaaa = aaaaaa->
aaaaaaaaaaaa()
->
aaaaaaaaaaaaaaaa(
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
->
aaaaaaaaaaaaaaaaa();
