Fix an issue whereby ANSI escape characters could appear in search
output when a pager was not configured.
The root cause of the problem was code that was overzealously applying
an underlying effect to search terms.
This commit simply rips out underlying entirely, both as means of
resolving this problem, and also simply for removing needless visual
noise from search output.
- Corrects an error with `--search`. Previously, `--search` was not
aware of whether it was outputted to a TTY, and would apply colorization
at all times. This resulted in unwanted behavior when, for example,
piping search results into a paginator.
- Corrects an error with `--color`. Previously, `--color` would be
ignored if output was being written to a non-TTY. This made it
impossible, for example, to `cheat tar --color | less -R`, as
colorization would always be stripped. The behavior of `--color` has
been modified such that it now behaves similarly to `--color=always` in
other applications.
- Re-implemented the project in Golang, and deprecated Python entirely
- Implemented several new, long-requested features
- Refactored cheatsheets into a separate repository
