False "Recursive loop..." error

[phoenix-violeus]

Issue summary

When printing (echo/less) via server-side invocation, output that mirrors that of the previous command throws an error:
Recursive loop in echo detected, skip

Expected behavior

Output should print error-free after both submissions

Actual behavior

The second submission prints only an error message

Steps to reproduce

Client-side:

$(function() {
    $('body').terminal(function(command) {
        return $.post('script.php', {command: command});
    }, {
        invokeMethods: true
    });
});

Server-side (script.php):

<?php
echo '[[ terminal::less("Testing...") ]]';

Those recursive guard is pretty flaky, maye I should remove it, and if it create recursive loop, it will be user problem. Will check if I can fix this without removing this check and if not I will just remove it.

Thanks for the report.

No problem and thanks for the terminal!

The issue is fixed, it should never give false positives when detecting recursive calls.
