Subject: Testsuite: Provide '>>> ' for script input to allow binary data
X-Git-Url: https://git.exim.org/users/heiko/exim.git/commitdiff_plain/f7ec095232186edba2b7137594bfdd7d7b7f9504?hp=f093e580a55ad4d41a3ba70bae265b131b5c3bbb

Testsuite: Provide '>>> ' for script input to allow binary data

This mimics the '>>> ' prefix for the test client. Any line prefixed
with '>>> ' will be processed by Perl's string eval().

As '>>> ' is generic and documented, it replaces the
(undocumented) '\NONL\' tag.

+If the input line starts with '>>> ', this prefix and any trailing spaces
+(including line feed) are removed. The reminder is processed with Perl's string
