This looks good to me, once the build warning is fixed!
I think there is a follow up though, for both compression & decompression:
zstd -c --progress /path/to/file > /dev/null
zstd -dc --progress /path/to/file > /dev/null
In both of these cases, no newline is printed at the end of compression. Normally, the progress is replaced with a status line, like these commands:
zstd /path/to/file -o /dev/null
zstd -d /path/to/file -o /dev/null
I think we should either:
- Add a
\nafter the last progress message. - Also print the final status line with
--progress.
I don't have a super strong preference, but I would go with (2) unless we have an explicit reason why we chose not to.

This seems separate from the --progress notification issue.
This message is more part of the final status.
And I don't believe that this additional information (time spent) belongs to default, which should remain restricted to 1 line.
We may have room for discussion in determining if it's more appropriate for level 3 (-v) or 4 (-vv),
but it should certainly not be part of 2 (default).

This was added per Nick's comment suggesting we add the final status line when using --progress to overwrite the last progress message; it will still remain at level 4 in absence of the progress flag

The final status line is just the line specifying the final size and compression ratio.
Information about timing and speed are considered supplementary (and do constitute an additional line).
