* The Range class defines continuous range of character.

* endChar) defines the first character AFTER the range (i.e. it doesn't belong the range).
* (endLine, endChar) must be a valid character inside text, except EOF case.
*
* <p>Special cases:
*
* <ul>
* <li>Zero length range: (startLine, startChar) = (endLine, endChar). Range defines insert
* position right before the (startLine, startChar) character (for {@link FixReplacement})
* <li>EOF case - range includes the last character in the file:
* <ul>
* <li>if a file ends with EOL mark, then (endLine, endChar) = (num_of_lines + 1, 0)
* <li>if a file doesn't end with EOL mark, then (endLine, endChar) = (num_of_lines,
* num_of_chars_in_last_line)
