+ For zlib & zlibx compression the valid values are from 1 to 9 with 6 being
the default. Specifying 0 turns compression off, and specifying -1 chooses
the default of 6.

+ For zstd compression the valid values are from -131072 to 22 with 3 being
the default. Specifying 0 chooses the default of 3.
- For lz4 compression, there are no levels available, so the level is always
- 0.
+ For lz4 compression there are no levels, so the value is always 0.
If you specify a too-large or too-small value, the number is silently
limited to a valid value. This allows you to specify something like
`--zl=999999999` and be assured that you'll end up with the maximum
compression level no matter what algorithm was chosen.

+ If you want to know the compression level that is in effect, specify
`--debug=nstr` to see the "negotiated string" results. This will report
something like "`Client compress: zstd (level 3)`" (along with the checksum
choice in effect).
