Corrected the parsing for assignment left-hand-side to allow for

whitespace inside the array declaration, as was (correctly) done
for pin connections.  Previously, "assign x[ 0] = 1'b1" would
fail due to "x[" being parsed as a token by itself.  Now, upon
reading an array opening bracket delimiter, the verilog parser
will continue to read tokens until it finds the closing bracket,
as it does for pin connections.
