Incorrect parsing of OSC 8 hyperlinks

I see all the coreutils man pages on man7.org are corrupted,
due to the misparsing of OSC 8 hyper links output by --help.

As a quick fix you can set the TERM=dumb environment variable
which will suppress these escapes.

Note the help2man that is shipped with coreutils (in man/help2man)
is updated to support these escapes.

The escaping should be quite easy to parse though,
if you wanted to implement full support.
For example the arch html generator supports this as can be seen at:
https://man.archlinux.org/man/tee.1

thanks,
