The cardinal rules of indentationSam Deep Moss Ankle Edelman Leather Millard Boot Women's qp4qZ
- A line should be indented past the position of the parenthesis that starts the list to which the beginning of the line is an element.
Victoria's Vibrant Slipper pom Large Size Red Secret Pom TwIxTr This rule must not be violated under any circumstances. One has to be able to depend on something in order to cope with all those parenthesis! Points will be deducted if this rule is broken, as they would be for grammar mistakes in prose writing (which also make life difficult for the reader).

Room for variation
As the ok examples show, these rules still allow a lot of freedom. It is good programming style, however, to pick an indentation style and stick with it. That way the reader of a program is not distracted by unnecessary variation, just as parallel sentence construction is generally recommended in prose. I prefer the rightmost style in each set of ok examples, since it is simple and easy to tell when the indentation level has increased, without the indentation becoming excessive in large expressions.
There are no absolute rules for how much to put on a line. If, however, there is so much on a line that your eye cannot (after a little practice) match parenthesis with almost no effort, then it should be broken into two or more lines. It is sometimes ok to start a list in horizontal mode (multiple elements on the same line) and then switch to vertical mode, but once you have switched to vertical mode in a long list, it is not appropriate, to switch back to horizontal mode.
