This commit strips OSC (Operating System Command) sequences before
printing lines. Eventually when time permits, I want to add back
support for printing OSC sequences (and improve it to treat hyperlinks
like an attribute).
Until then, this should help prevent garbled output :)
This can be used to extract a subset of ANSI escape sequences from a
string of text. I have big plans for this eventually, but for now, it'll
be used to strip OSC before printing.
This reverts commit 8174e022797924aec735ff440806920767f80496. Turns out
it is needed for a common use case, see
https://github.com/sharkdp/bat/issues/2307.
It is not a clean revert, because I adjust CHANGELOG.md and also add a
comment to the test. I also had to resolve a small `use` conflict.
