Clink incorrectly shows certain commands as quoted

[gamer191]

The command echo "hi^"&calc" will show everything after the word "echo" as quoted (yellow). This is incorrect, because the quotes escape the escape character, leaving the 2nd quote unescaped

This could be a minor security issue, as users could hypothetically be social engineered into running a command with an escaped end quote

Thanks for reporting this.

This led to finding lots of subtle quirks in parsing of ^ and " and @ in various contexts.

Several recent commits have fixed this, and various related quirks.
