- A redirection error is only fatal (meaning the execution of a shell script is
terminated) for special built-ins. Previously it was fatal for all shell
builtins, causing problems like the one reported in PR 88845.
- Variable assignments remain in effect for special built-ins.
- Option or operand errors are only fatal for special built-ins.
This change also makes errors from 'fc' non-fatal (I could not find any reasons
for this behaviour).
Somewhat independently from the above down-grade the error handling in the
shift built-in if the operand is bigger than $# from an error() call (which is
now fatal) to a return 1. I'm not sure if this should be considered a POSIX
"operand error", however this change is needed for now as we trigger that error
while building libncurses. Comparing with other shells, zsh does the same as
our sh before this change (write a diagnostic, return 1), bash behaves as our
sh after this commit (no diagnostic, return 1) and ksh93 and NetBSD's sh treat
it as a fatal error.
all column-headers to print in lowercase by default. I was in too
much of a rush in committing 1.75, and didn't notice that the case
had changed. This time I did considerably more testing, and used
'diff' instead of just quickly eyeballing the results...
Apologies. I expect this means the dunce cap is mine for awhile.
If this doesn't work, I'll just drop back to 1.72 and hide under
my desk for awhile.

arguments to be passed after the file. For compatibility (we even use that
feature in buildworld) additional arguments are not considered to be an
error, even though this shell does not do anything with the arguments at all.

flag to use a time other than modtime (-c, -u, or -U), the output would
actually be sorted by the specified time rather than size. This does
alter the behavior in the case where both -S and -t are specified. Now,
-S is always preferred. Previously, -t was preferred if one of -c, -u, or
-U was specified, and -S was preferred otherwise. Perhaps -S and -t should
override each other (last one specified wins).

The tcsh 6.14 uses libiconv to convert catalogs to appropriate charset
dynamically. However, we don't have libiconv in our tree. So, I made
some hack to load libiconv dynamically. If libiconv is available, you
can use catalogs for more locales than the locales which catalog is
actually installed.
To use this feature, you need to symlink catalogs to appropriate
locales. You can do this by installing ports/shells/tcsh_nls.

This makes a difference for the trap builtin, where after "trap '' 0" we
printed "trap -- quit". This is wrong, because an empty action means to reset
the action to the default. A side effect of this commit is that empty
variables are now printed as "variable=''" instead of just "variable=".

implementation directly calls getrusage() to get the times because this is more
convenient.

just mean "do not automatically set -A for root". That is, if -A
is explicitly set, -I is ignored. Also, document -I in usage().

using longjmp which is obviously a bad idea during malloc calls.
Note: I think there is still a small race here because volatile sig_atomic_t
only guarantees atomic reads and writes while we're doing increments and
decrements.

earlier, and more gracefully. Previously, this combination would be
ignored early in the code where permissions are tested and fail later
with a very unhelpful "permission denied" error.
Instead, test for this flag in the same block that generates the
"override?" messages for read-only files, but instead of trying
to guess what the user has in mind, generate an error and exit.
Update the man page to reflect this new behavior.
