Contradictory indentation errors with multiline type parameter list

[bethcutler]

If a code snippet contains a multi-line type parameter list, ktlint may produce contradictory errors with the experimental indentation rule.

E.g. for this code snippet

object TestCase {
  inline fun <
    T1,
    T2,
    T3> create(
      t1: T1,
      t2: T2,
      t3: T3
  ) {
    // do things
  }
}

... ktlint produces this errors for each function parameter line (t1, t2, t3):

Unexpected indentation (6) (should be 4)

If the indentation on the function parameter lines is "corrected" like so

object TestCase {
  inline fun <
    T1,
    T2,
    T3> create(
    t1: T1,
    t2: T2,
    t3: T3
  ) {
    // do things
  }
}

... ktlint is still not satisfied, now producing this error on each of those lines:

Unexpected indentation (expected 6, actual 4)

Probably could be covered by #587

@Tapchicoma Added PR: #804 to enforce this behavior. However, it is unclear if we want to make this an enforced rule:

object TestCase {
  inline fun <
    T1,
    T2,
    T3> create(
    t1: T1,
    t2: T2,
    t3: T3
  ) {
    // do things
  }
}

to

object TestCase {
  inline fun <
    T1,
    T2,
    T3> create(
      t1: T1,
      t2: T2,
      t3: T3
  ) {
    // do things
  }
}

since the default spacing seems to leave the indentation flat.

If we want to leave it as is, then I think we can close out this issue.
