Allow vertical pipe (|) to anchor beginning of match. Otherwise, angle bracket match option may cause
<code></code> span to cross table cell boundary for sequential cells containing @<…>@.
Leave trailing whitespace. Trailing whitespace may not be symmetric with leading whitespace, so
shouldn't be removed. Removes necessity of including multiple spaces between (admitted unlikely)
consecutive <notextile></notextile> instances.
Changed regex in textile.doSpecial() to:
<code></code>
span to cross table cell boundary for sequential cells containing @<…>@.<notextile></notextile>
instances.Added test: textile.tests:Tests.testAtSignAndNotextileInTable
