Previously netstat would print the whole line of an ip address or
resolved hostname. If the hostname was longer than the address column
length, it would push following columns into disaligned output.
This sets the default behavior to truncate any IP address or symbolic
hostname that is larger than the maximum address column size to provide
cleaner output. In the event the user wishes to see the whole address
name, they can then pass the wide option that will output as wide as
necessary to print the whole name.
This adds the ability to hide certain options from certain help texts.
`--complete` is always hidden, whereas `--help` and `--version` are
hidden from Markdown help text only.
Note that in all cases these three options are hidden from the short
usage line.
This set was hand-curated, guided by the questions:
- Does it have at least three options, i.e. is the help page
non-trivial?
- Is the program unusual, i.e. does listing it in Help or on
man.serenityos.org spread awareness?
- Is the program common, but we only implement a subset of 'common'
flags?
