don't read-uninitialized for \177 in a here-doc
A DEL (0177, dec 127) byte in a here-document would cause dash to
access uninitialized memory at the end of one of the syntax.c
tables,
since those tables are sized to accommodate a maximum index of
BASESYNTAX + 126. Make the generated tables one byte larger.
printf ':<<\\E\n\200y\nE'|./dash
* src/mksyntax.c (filltable): Use 258, not 257 as the size,
so that BASESYNTAX(=130) + 127 is a valid index.
(print): Likewise.
