extractIndentationFromTokens

Extracts the indentation portion from a list of elements. This method differs from computeFromPrecedingElements because it doesn't look for a newline first - it assumes the list represents tokens after a newline and simply extracts all leading whitespace. This is useful when we have already collected preceding tokens and want to extract just the indentation part.

Return

list of indentation elements (leading whitespace only)

Parameters

precedingTokens

tokens that precede the position
