Unable to match links ended with \u001B rather than \u0007.

[avivkeller]

ansi-regex cannot match link regexes that end in \u0001B, as the regex only allows \u0007.

Example: \x1b]8;;http://example.com/\x1b\\This is a link\x1b]8;;\x1b\\ hello
Reference: nodejs/node#53697

For anyone digging into this, "OSC" is an "Operating System Command". One reference I've found is from Microsoft, which claims:

As OSC sequences, they are ended with a String Terminator represented as and
transmitted with ESC \ (0x1B 0x5C). BEL (0x7) may be used instead as the terminator,
but the longer form is preferred.

So the bug should probably read "cannot match link regexes that end in \u0001B\u005c".

I've verified that iTerm2 at least does accept the sample string, so this isn't just a Microsoft thing.

wiki says that 0x9C and 0x1B 0x5C (ESC ) are both standard STs and should be supported; I wish there were a real spec but it seems like practice is all we have here.

The OSC8 spec uses 0x1B 0x5C, for whatever that's worth.
