Its not posix compliant and serves very little purpose.
With this change compat and jobs modes are consistent wrt how
they treat each line of a script.
Add support for the '+' command line prefix as required by posix.
Lines prefixed with '+' are executed even when -n is given.
[Actually posix says they should also be done for -q and -t]

Instead of adding MAKE_BOOTSTRAP for hosted environments, i.e., when
you want things simple, instead add MAKE_NATIVE to get those hugely
important features like __RCSID().
It's now possible to build make on some hosts with: cc *.c */*.c
Notes:
* The immediately previous version of make errored out on --,
which is what needs fixing.
* Historic bsd make silently ate -- and continued to process
options, so this is a behavior change from that, too, but presumably
there is more to gain in fixing it than in being bug-compatible.
This makes it possible to use expressions like
${("${LIST:Msomething"}):?present:absent}
it also makes treatment of lhs and rhs more consistent, and
makes CondToken easier to read.
Update unit-test/cond1 to test new features.
No functional change under NetBSD.
Restarting a getopt(3) loop is an extension to the posix getopt(3)
behavior and is not portable.

- new dir.c function: Dir_FindHereOrAbove:
Search for a path in the current directory and then all the directories
above it in turn until the path is found or we reach the root ("/").
- add hooks to use it in main.c for -m and syspath (compiled in
_PATH_DEFSYSPATH and $MAKESYSPATH).
- updated man page
Improve description of variable modifiers.
In the variable list, be more specific referring to "environment variables"
rather than just relying upon the formatting difference between .Ev and .Va.
Using -e in sh/ksh to stop on error doesn't work with grouped commands. At
least for any SUSE compliant sh(1). Instead, extend the Shell struct and add
errOut which provides a template to use to check error status from commands.
objdir) try opening the file from curdir and if that fails try from objdir.
This way .depend files get picked up via their full path names rather than
just .depend so vars like PARSEDIR, PARSEFILE are then set correctly. This
fixes PR#13289 reporting incorrect pathnames for .depends with errors in
them
In the "modifier description" list, show each modifier with the leading `:'.
Rationale: it's hard to search for modifiers without it, and we already do
the same thing in the -options and .makecommands lists. I now find it much
easier to find the description for a modifier in the man page.
* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h
* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.
These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).
