Formatting broken if function statement is written over multiple lines

[gustason]

For example,

function GetDLC returns character
():
    define variable cValue as character no-undo.
end function.

gets formatted as

fu:
ction GetDLC returns character
    ():
    define variable cValue as character no-undo.
end function.

This kind of erroneous formatting doesn't seem to occur when blockFormatting is disabled, therefore, the problem might be in that.

I found that the problem is in the colon code of the BlockFormatter, as it always assumes that the colon will be on the first line.
