[Enhancement] provide option for a narrow output (fewer spaces)

I would appreciate it to have an option to make the output less wide, especially for long listing:
- no spaces or only one space at the beginning
- only one space between the columns (i.e. owner, group, size,...)

The issue names no file or test. Start by locating the CLI code that formats long listings and trace how spacing is applied at the beginning and between owner, group, size, and other columns. Done means an option produces the requested narrower output without changing the default formatting.
