Sam Atkins 8461f8c1cd Help: Add support for launching with a section and page, like man
I found it strange that `man` and `Help` did not accept the same command
line arguments since they are so similar. So... now they do. :^)

This means you can now open for example the `tar` man page in Help with
`Help tar`, or `Help 1 tar` if you want to disambiguate between pages in
different sections.

If the result is not found, it falls back to the previous behavior,
treating the input as a search query.

Initially I had this written as two optional positional arguments, but
when told to parse `[optional int] [optional string]`, and then given a
string input, ArgsParser forwards it to the [optional int], which then
fails to parse. Ideally it would pass it to the second, [optional
string] arg instead, but that looks like a fairly big change to make to
ArgsParser's internals, and risk breaking things. Maybe this ugly hack
will be an incentive to fix it. :^)

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

I (Andreas) regularly post raw hacking sessions and demos on my YouTube channel.

Sometimes I write about the system on my github.io blog.

I'm also on Patreon and GitHub Sponsors if you would like to show some support that way.
