Inconsistencies in if formatting

[ovatsus]

In most of the places where if have something like:

if a then
    b
else 
    c

fantomas changes to

if a 
then b
else c

which is fine. But why did it then turned this:

            ||> Array.foldBack (fun line (currentLine, allLines) ->
                if line.StartsWith ("i," + DateTime.Today.ToString("MM/dd/yyyy"))
                then "", line + currentLine :: allLines
                else line + currentLine, allLines)

into this?

            ||> Array.foldBack (fun line (currentLine, allLines) -> 
                    if line.StartsWith("i," + DateTime.Today.ToString("MM/dd/yyyy")) then 
                        "", line + currentLine :: allLines
                    else line + currentLine, allLines)

I'd prefer to keep the then aligned with the else. What was the reason?

The formatting of SynExpr.IfThenElse was revisited in #557.
An attempt was made to align with the F# style guide.
