modifiers. The paragraph that explains the difference between ${foo:-bar}
and ${foo-bar} etc. was not very visible.

6da31df83b Make this compile with DEBUG defined now that WARNS=0 has been removed
from the Makefile:
- Print pointers with %p instead of %x.
- Include missing headers to get prototypes.

c121fd80b8 Do not strip CTL* escapes from redirection filenames in argstr(); they
are later stripped with rmescapes() in expandarg(). If the filename has
already been unescaped, doing it again in rmescapes() can walk off the
end of the string, leading to memory corruption and eventually SIGSEGV.

427748f7df Disallow empty condition parts of "if", "while" and "until" compound
commands. Commands like "if then ... fi" and "while do ... done" are no
longer accepted. Bodies of compound commands are still allowed to be
empty, because even though POSIX does not allow them, most shells do.

54beeb39c2 Use %d in a printf() format string and cast the argument to int instead of

7e73d40ee5 Replace a home-grown printf() clone with a fwopen() wrapper around
libc's vfprintf() that writes to a `struct output' instead of a file.
Inspired by NetBSD's similar changes (they used asprintf() instead).

ec65e9977a Use the %t format modifier to print differences between
pointers.  This fixes two format warnings on 64 bits
archs which are fatal now that WFORMAT=0 has been removed.

It doesn't fully fix the sh(1) build on 64 bits platforms
though, there is still some quad_t issues that need to be
fixed.

b7f23f5be5 Remove WARNS=0 and WFORMAT=0. The shell compiles cleanly at WARNS=2
on at least i386. If there are warnings on other archs, I'd rather hear

b1a667509b Remove bits and pieces of support for atty, which was made obsolete by
adding history and vi/emacs-style line editing to the shell itself.
Atty was a user-mode terminal emulator (like screen and window) that did
line editing and history.
