Tab indentation replaced by space indentation in PHP files in 1.4.0

[BozzaDaniel]

In version 1.4.0 the indentation is replaced by spaces if using tabs in PHP files. It doesn't happen in other formats such as typescript. The following example:

<?php
	$test = 123;
	$test123 = 456;

	if ($some_variable) {
		$testing = 'test';
		$testing_123 = 456;
	}
?>

Will result in this with 1.4.0:

<?php
 $test    = 123;
 $test123 = 456;

	if ($some_variable) {
  $testing     = 'test';
  $testing_123 = 456;
	}
?>

Instead of this (in 1.3.2):

<?php
	$test    = 123;
	$test123 = 456;

	if ($some_variable) {
		$testing     = 'test';
		$testing_123 = 456;
	}
?>

This is happening on any type of file as of 1.4.0

Seems we need consider more complex case, for example, what if align with mixed whitespce, for example:

	$test    = 123;  // This line contain 1 tab
        $test123 = 456;  // This line contain 8 whilte sapce

@chouzz seems like this is still a problem:
