* match.c (do_txeval): Lift an annoying restriction in the pattern
language's expression evaluator. Whereas TXR Lisp expressions can be
used int the pattern language, preceded by @, it was not possible
to evaluate TXR Lisp variables this way. So instead of @var,
some clumsy trick had to be used like @(identity var). This is not
necessary any more. Code like @(next @*stdin*) will now work.
* txr.1: Updated.
