This commit introduces a `SoftWrap` option that adjusts the behavior of the `Lines` option and `ShowLineNumbers` when used with the `Wrap` option. - `Lines`: Currently, when both `Lines` and `Wrap` options are used, the line count is computed after wrapping occurs. This can lead to discrepancies where wrapped lines count as multiple lines, causing the final output to exclude some original input lines. With the new `SoftWrap` option, wrapped lines will count as a single line, ensuring that all lines specified in the `Lines` option are correctly included. - `ShowLineNumbers`: When `SoftWrap` is enabled, line numbers are not added to wrapped lines. This preserves the original line numbering, ensuring consistency with the input file.
The highlighting is done by applying a grey background with 50% opacity
to all selected lines.
The parsing of the option is as follows:
- Each input (lines or line ranges) is separated by ;
- To provide a range, "-" separates the start and the end of the range.
- In a range, both start and end are required, and end must be greater than start.
