CoffeeScript indentation

gistfile1.rb

a = b = c = 0

# This works.
# Note how the 2nd line is indented so "b" in 2nd line
# is in the same column as "a" in 1st line.
if a is b and
   b is c
  console.log 'works'

# This also works, but is ugly.
if a is b and
b is c
  console.log 'works'

# This doesn't work because the "if" line needs some indication that
# the expression continues on the next line ... like ending with "and".
# Adding parens around the expression apparently isn't enough.

if (a is b
and b is c)
  console.log 'works'

function1 = (p1, p2, p3, p4) -> console.log 'in function1'

function2 = (p1, p2, p3) -> console.log 'in function2'

# This works if the 2nd and 3rd lines have the same indentation.
# No other indentation of the 3rd line seems to work.
