text/scanner: don't crash when calling TokenText in error handler Make sure Scanner.tokEnd is set before we call Scanner.Error and update documentation accordingly. (Until now tokEnd was only set before returning from Scan, so a call to TokenText during error handling may have crashed.) While at it, tighten a check in Scanner.TokenText to ensure Scanner.tokEnd >= Scanner.tokPos if we have a token. Also, silence error messages to Stderr in unrelated TestIllegalExponent. Fixes #29723.
