Forbid (temporary or permanent) modifications of the strings in NARG nodes
during expansion.
Tilde expansion now needs to copy the username for the terminating '\0'.
Per POSIX, 'cd -' should use the OLDPWD shell variable, not internal state.
This variable is normally exported.
Also, if OLDPWD is not set, fail 'cd -' instead of changing to the current
directory.
Some variables like PATH call a function when modified. Make sure to call
this also when leaving a function where such a variable was made local.
Make sure to restore local variables before shellparam, so getopts state is
not clobbered.
Redirect 'cd -' output to /dev/null since POSIX requires it to write the new
directory name even if not interactive, but we currently only write it if
interactive.
Command substitutions containing a single simple command and here-document
expansion are performed in a subshell environment, but may not fork. Any
modified state of the shell environment should be restored afterward.
The state that OPTIND=1 had been done was not saved and restored here.
Note that the other parts of shellparam need not be saved and restored,
since they are not modified in these situations (a fork is done before such
modifications).
With the new expand.c code, the intermediate representation passed to the
pathname generation code only contains CTLESC, not CTLQUOTEMARK.
CTLQUOTEMARK now only occurs in the text of NARG nodes (output of the
parser).
This avoids the need to add and remove CTLESC bytes if pathname generation
will not be performed (set -f).
Side effect: the order of operations is slightly different: pathname
generation in ${$+* $(CMD)} will not see filesystem changes from CMD.
This simplifies the code and should be faster in some cases.
Side effect: the order of operations is different so that the value of IFS
used when IFS is modified during expansion (${IFS:=...}, ${IFS=...} or
$((...IFS=...))) may be different. Note that this order is highly unportable
between shells.
Latest update of locales introduced abbreviated month that follows the regionale
rules meaning that they can be of variable length instead of being arbitrary
truncated to top 3 characters.
To fix alignement, ls now computes the visible length of the abbreviated month,
pads the shorter month with spaces in order to make sure everything is properly
aligned

Unfortunately filemon/meta mode tracks all indirect dependencies here
since ld(1) is reading libelf when linking in libkvm. Churn would be
reduced if this was able to be limited to direct dependencies.

Tracking these leads to situations where meta mode will consider the
file to be out of date if /bin/sh or /bin/ln are newer than the source
file. There's no reason for meta mode to do this as make is already
handling the rebuild dependency fine.

This simplifies the code (e.g. allowing use of qsort(3) instead of a
hand-rolled mergesort) and should have better cache properties.
The waste of unused args arrays after resizes is approximately the same as
the savings from getting rid of the next pointers.
At the same time, remove a piece of global state and move some duplicated
code into a function.
