I think this is a duplicate bug, I am sorry. This patch has already been
reviewed and accepted by Lars Ingebrigtsen.

This setting accepts a free-form write-in. There may be more Latex
environments satisfying the "tabular" protocol, not just "tabular"
itself and "longtable". I haven't done an extensive survey, but I
suspect that most do. If this value is interpreted as a symbol, it
would require a "symbol->string" at the time of actually writing
the code into the final buffer. I don't think that a symbol would
really fit here.
