Martin Cracauer b5803eae6a Disable part of my 8-bits fixes from December 1999.
Serious fix still needed, see discussion on -current
(Subject: /bin/sh dumps core with here-document of 8bit text)

Martin Cracauer d753a42598 Fix type builtin for absolute paths and relative paths with directory
names in them.

Also use a colon in the answer of `type` everytime the questioned item
is not usable.

Martin Cracauer 84c3800cdc From submitter:
growstackblock() sometimes relocates a stack_block considered empty
without properly relocating stack marks referencing that block.
The first call to popstackmark() with the unrelocated stack mark
as argument then causes sh to abort.

Relocating the relevant stack marks seems to solve this problem.

The patch changes the semantics of popstackmark() somewhat.  It can
only be called once after a call to setstackmark(), thus cmdloop() in
main.c needs an extra call to setstackmark().

Martin Cracauer d62ec71c31 Rename the trace() function (that is build only in the -DDEBUG=2
case), so that it doesn't clash with the ncurses function of the same
name when linking statically with -ltermcap.

The linker only complains when -static is used, and it is not clear
whether this is a bug.

Martin Cracauer f01e3d0cfe Fix warnings, some of them serious because sh violated name
spaces reserved by the header files it includes.

mkinit.c still produces C code with redundant declarations, although
they are more harmless since they automatically derived from the right
places.

Sheldon Hearn c644db6aa2 Improve shell documentation:
* Consistently misspell built-in as builtin.

* Add a builtin(1) manpage and create builtin(1) MLINKS for all shell
  builtin commands for which no standalone utility exists.  These MLINKS
  replace those that were created for csh(1).

* Add appropriate xrefs for builtin(1) to the csh(1) and sh(1) manpages,
  as well as to the manpages of standalone utilities which are supported
  as shell builtin commands in at least one of the shells. In such
  manpages, explain that similar functionality may be provided as a
  shell builtin command.

* Improve sh(1)'s description of the cd builtin command. Csh(1) already
  describes it adequately. Replace the cd(1) manpage with a builtin(1)
  MLINKS link.

* Clean up some mdoc problems: use Xr instead of literal "foo(n)"; use
  Ic instead of Xr for shell builtin commands.

* Undo English contractions.
