Improve usability of head(1) and tail(1):

[delphij]

Summary

• Consistently support -q (quiet) and -v (verbose)
• Allow specifying numbers with SI prefixes supported by expand_number(3)
• Remove 2^31 limit on lines for head(1)

usr.bin/head/head.1

88–93

Moving these up to just under

.It Fl n Ar count , Fl -lines Ns = Ns Ar count
Print
.Ar count
lines of each of the specified files.

would make for better flow IMO.

Update manual page per reviewer suggestion.

The rendered page would be:

-c bytes, --bytes=bytes
        Print bytes of each of the specified files.

-n count, --lines=count
        Print count lines of each of the specified files.

        Both count and bytes may also be specified with size suffixes
        supported by expand_number(3).

(The indentation was somewhat weird in my opinion, does this look good, or do you have some suggestion in the markup?)

Looks good to me (carefully read the code, but didn't compile and execute it). It would be great if you can add some simple tests to guard those new features.

Good point. I don't know. Unless removing .Pp does the trick, someone more familiar with mdoc will have to answer.

[delphij]

Add test cases for new features.

LGTM for the man page parts.
