Yet one more addition to error handling

Dear List,

I found one more error in the sql reader macro. Turns out that when
SLIME reads a file, if there's an error it tries to find the location of
the error. To do this, it has to re-read the file, but this time with
*read-suppress* turned on, as mandated by the CLHS.

This means that (read-delimited-list) will return NIL.

This patch causes this to be handled properly.

I think I'm getting the hang of this lisp thing.

Sorry for the patch spam,
Alan
