v1.23.11: Fix unknown-terminal-bg color handling

Before this release, we just didn't highlight in this case.

With this change in place, we now fall back on the default dark theme when background color detection fails.

Fixes #202

v1.23.10: Fix highlighting of compressed files

With this release, doing moar README.md.gz will properly highlight the transparently uncompressed file as Markdown.

Fixes #204.

v1.23.9: Prevent a crash

Fixes #198

v1.23.8: Support `sudo` password prompt

Before this release, if you did sudo whoami | moar, moar would prevent you from entering your password at the sudo prompt.

With this release, moar will wait for the first byte to arrive before bringing up its UI, enabling you to enter your password in peace.

Fixes #199.

v1.23.7: Hide line numbers on man pages

By default. Press left arrow to get them back. Or use start moar with --no-linenumbers=false.

man starts by checking the terminal width, and then formats man pages to fit that width.

Then, if moar adds line numbers, the rightmost part of the man page will be shifted out of view.

So we try to detect showing man pages, and in that case disable line numbers so that the rightmost part of the page is visible by default.

v1.23.6: Pretend `.tgz` files are gzipped text files

If the archive contains text files, this can let you to read those text files.

Note that this does not imply support for viewing archives. moar is not an archive viewer. If it breaks, you get to keep both pieces.

v1.23.5: Use 24bit colors if COLORTERM says we can

Also print some more environment variables with --help if set, since these affect moar's default behavior:

• TERM
• TERM_PROGRAM
• COLORTERM

v1.23.4: Improve Rio terminal support

Also, on --help, print all *PAGER environment variables. This could help troubleshooting.

v1.23.3: Fix escape codes being printed on the terminal

Before this change, if you ran moar with --quit-if-one-screen and manually set a style using --style, you could sometimes get escape sequences printed on the terminal after moar exited.

In this release, that should not happen any more.

v1.23.2: Try preventing control codes on the terminal

Caused by terminal background color detection code. Give it more time and print it on the alt screen.
