Fixing gaping bug in the handling of @-delimited expressions
within quasiliterals. This has been a problem for years.
Quasiliteral strings existed very early before TXR Lisp was introduced.
So it made sense that when @ is seen in a quasiliteral, the
lexical analyzer pushed into the SPECIAL state in which directives
are recognized, like in the pattern language. I noticed
this because there is an @(if) directive now, which prevents
`@(if ...)` from being valid.
* parser.l (QSPECIAL): New scanner state. This is a state
similar to SPECIAL that we enter into when @ is seen in a QSLIT state.
In this state we recognize constructs like braced variables, but not
certain other features like directives.
