Allow extra spaces for alignment inside line continuations only

[Chuck]

This is a controlled violation of the "you cannot mix tabs and spaces" rule.

An example:

class X

	def fooBar(i as int,
			   j as int) as int is shared
		return i + j

	def main is shared
		assert .fooBar(2, 3) == 5

That example will make more sense when viewed in your editor. The "j as int) ..." line is indented with TABs like the rest of the source, but then 3 additional SPACEs are used to line up the j underneath the i.

• 1 - 3 spaces
• No more than 3
• Not allowed outside of line continuations
• Also, cook up the same example with spaces only, no tabs. (In that case there is no such detection as "1 - 3" spaces.)
• Test cases for TABs followed by 4 or more spaces producing an error.
