🪲 Allow comments to be indented #3287

[boryanagoncharenko]

Fixes #3287
The PR addresses multiple small issues related to comments and trailing spaces. Automated tests are added for all scenarios.

How to test

1. Indented comments and comments at the end of code blocks should work in levels 9-11 without errors:

repeat 3 times
    # comment
    print ‘3’ # another comment

2. The print command should be able to print a # sign in levels 4-18:

print 'comments start with the # sign'

3. Equality checks should preserve the original whitespacing of its arguments in levels 8-11. The following program should print the value of i.

i = this   is
print '[' i ']'
if i = ‘this   is’
  print i
