Fix the way the 'read' builtin processes IFS. In particular:
...
- IFS whitespace is now processes correctly,
- Trailing non-whitespace IFS characters are added to the last variable
iff a subsequent variable would have been assigned a non-null string.
Now passes the 'read' tests in http://www.research.att.com/~gsf/public/ifs.sh

expbackq() was incorrectly backing up a temporary buffer when removing \n
...
from the end of output of commands inside $(...) substitutions.
If the program output is n*128+1 bytes long (ending in a \n) then the code
checks buf[-1] for another \n - looking an uninitialised stack.
On a big-endian system an integer of value 10 will satisfy this (unlikely
on little endian) and can happen depending on the last code path to use
a lot of stack!
This caused the problem with newvers.sh on sparc64 after ', 2005' was
added to the date list.

PR/25699: David Laight: sh(1) hangs opening a named pipe as stdin for

background process
This happens because we vfork, and then open a named pipe with O_RDONLY

and then reset it if we are vforked. XXX: this is an ugly fix.

Make "set -e" once again provide the behavior documented in the man page,
...
which was unnecessarily changed in revision 1.50 while fixing other bugs.
That is, exit the shell if the last command in a || or && compound statement
is not short-circuited, and exits with a false status. I.e., the following
will cause the shell to exit:
set -e
false || false
While this is not the prescribed behavior in SUSv3, it is what our man page
documents, and it is what all of the following implementations do:
NetBSD /bin/ksh (pdksh)
bash
zsh
Solaris 9 /bin/sh
Solaris 9 /usr/xpg4/bin/sh
Solaris 9 /usr/bin/ksh
Tru64 /bin/sh

Put a syntax.c under CVS instead of building if with the mksyntax program.

Kill mksyntax.c - no longer possible to get the 'wrong sort of chars'.
/bin/sh now has no helper binaries.
syntax.c uses C99 initialisers, run time initialisation could be used

I've used some #defines to help make this possible - but writing the code
starts making it rather messy.
