This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
while remaining (becoming :) compatible with other popular shells.
Specifically these changes include:
1) Implement 'trap -l' to get a list of valid signals names. This
is useful if you wanted to do something like reset all signal
handlers to there defaults values, in which case something like
this will do the trick.
trap `trap -l`
2) Reformat the output of 'trap' so it can be saved and later eval'd
to restore the saved settings.
3) Allow the use of signal names as well as signal numbers.
4) Fix trap handling of SIGCHLD so that commands like the following
(albeit, contrived) won't cause sh(1) to recurse ad infinitum.
trap uname 0 20
5) Make variables static that are used only in trap.c.
6) Minor 'style(9) police' mods.
now handles the getpwd() init problem the same way as bash
and ksh do. Also while I was in here, I cleaned up the format
a little, removed some unnnecessary #if SYMLINKS cruft, and
changed the pwd builtin to use getcwd(3) as Joerg suggested.
getopts should now work as expected. This fix was in the NetBSD
code that I was merging from but missed getting into FreeBSD's
version because of 'drain bamage' on my part.

isofs while the df command itself used the name iso9660fs or
cdfs. Both of these were inconsistent with the name cd9660 which
is used by the mount command. I modified df to recognize all of
the names cd9660, cdfs, isofs, and iso9660fs, and take them all
to refer to the same thing. Naturally I added a note of this
behaviour in the manual page too.

and he's right ... I forgot about this floating point stuff you can
use in user-land :-)
Increase precision of duration to microseconds.
No heuristics to avoid overflow in calculation needed - just depend
on DBL_MAX being a bit larger than LONG_MAX.
Use double instead of `struct timeval' in dd.h so that everything
doesn't have to include <sys/time.h>.
Fixed style bugs in recent and old FreeBSD changes.

This patch causes too many side effects, one of which bites hard is
when interrupting a 'make fetch' in the ports tree (PR#1990).
This whole area is a real can of worms....
This most definately should go into 2.2

so that simple regresssion tests based on `cmp' work. mkdep still
doesn't work right for these tools. They should probably be in
separate directories.
Sorted dependencies.

I've bumped into a few things that expected this switch to be present,
the most recent was the snmp package in ports. I'm not 100% sure of the
origins of this, but Linux has it, so does the "BSD-compatable" version
of ps on our SVR4 systems (so I assume SunOS has it too).
the 4.4 lite 2 tape as well. There are now only two diffs between
NetBSD's cat and FreeBSD's cat:
getopt return value is -1 on NetBSD and EOF on FreeBSD.
NetBSD has added setlocale calls before anything else.

"real" ksh does..
Also:
Reduce redundant .Nm macros in (unused) bltin/echo.1

- don't put \n on error() calls, error adds it already.
- don't prepend "ulimit" on error() calls in miscbltin.c.
- getopt typo on ulimit -p -> -u conversion
- get/setrlimit() calls were not being error checked
ulimit formatting cleanup from me, use same wording as bash on Bruce's
suggestion. Add ulimit arg to output on Joerg's suggestion.
merge of parallel duplicate work by Steve Price and myself. :-]
There are some changes to the build that are my fault... mkinit.c was
trying (poorly) to duplicate some of the work that make(1) is designed to
do. The Makefile hackery is my fault too, the depend list was incomplete
because of some explicit OBJS+= entries, so mkdep wasn't picking up their
source file #includes.
This closes a pile of /bin/sh PR's, but not all of them..

(Note, this is mostly going to be conflicts, which is expected. Our entire
sh source has a mainline, so this should not change anything except for
a few new files appearing. I dont think they are a problem)
