e8287f36b0 Skip soft hyphen when reading token 
The soft hyphen should only appear if a word is broken at the hyphen
position. Filter it out.

Adjust the entity test files to reflect the new behaviour.

This fixes Issue #224 and Debian Bug #830173.

e9f5910f1f Ensure VLA size is at least one (again) 
This is the same issue as commit 12c7b62a42 and should have been
included there.

'maxcol' can be -1 which results in a size of 0. The array is never
accessed with 'maxcol < 0', but zero length variable length arrays are
undefined behaviour.

12c7b62a42 Ensure VLA size is at least one 
Compiling with GCC 10.2 with -fsanitize=address,undefined valgrind
and opening the 'opions panel' reports:
table.c:1632:8: runtime error: variable length array bound evaluates to non-positive value 0
table.c:1266:11: runtime error: variable length array bound evaluates to non-positive value 0
table.c:1267:12: runtime error: variable length array bound evaluates to non-positive value 0

'maxcell' is initialized to -1 which results in a size of 0 during the
first iteration. Though the array is only accessed if maxcell >= 0,
using a variable length array with a size < 1 is undefined behaviour
(see e.g. C99 6.7.5.2,p5).

This closes issue #51 .

6a032f360b Support the button element as defined in HTML 4.01 
Patch from upstream, [w3m-dev 04411] on 2010-09-17, to support the
button element.  It is discussed upstream and incomplete, but enough
to login Launchpad.
