Gets the given {@code start} and {@code end} view positions offset to a header.
<p>
The {@code view} is expected to replace the header line endings {@code \r\n} to {@code \n} (e.g. so there's no invisible
newline ({@code \r}) characters when editing), as such the positions of the {@code view} need to be offset to match the
ones in the header.
<p>
<strong>Note:</strong> The {@code view} and {@code start} and {@code end} positions should be validated before calling
this method.

@param view the view that contains the contents of a header
@param start the start position
@param end the end position
@return the positions offset for the header
