Log Message:
Add check for space presence after comma in skin()

Check if comma is followed by space, otherwise it may lead to overflow in the
output buffer as space might be extra appended to the output buffer without
consuming anything from the input. This condition breaks the assumption that
length(input) >= length(output) while the code relies on it.
