2053f313bf Lexer and grammar rules for a RETURNING clause on DELETE/INSERT/UPDATE. 
Actually making this work, though, will involve a lot more code which will
likely slow down processing for the common case where there is no
RETURNING clause.  Furthermore, RETURNING seems to be of limited usefulness
and it is not standard SQL.  So we abandon it here.  These experimental
changes are parked in a branch as an historical reference.  If circumstances
changes, we might take up the cause again some day.

e81f879f51 In Lemon, factor the parser stack overflow detection logic out of the 
yy_reduce() subroutine and into the main parser routine, so that when overflow
is detected, it can exit immediately.  This saves a single conditional in
the main loop of the parser.

the generated C file.  (3) Enhance the lemon.html documentation.
