1fb3e6c2bb sh: Fix read with escaped IFS characters at the end.
Characters escaped with a backslash must be treated as if they were not in
IFS. This includes stripping trailing IFS characters.

699c9af55f sh: Add set -o nolog.
POSIX requires this to prevent entering function definitions in history but
this implementation does nothing except retain the option's value. In ksh88,
function definitions were usually entered in the history file, even when
they came from ~/.profile and the $ENV file, to allow displaying their
definitions.

This is also the first option that does not have a letter.

424480153f sh: Fix out of bounds read when there is no ] after a [:class:].
The initial check for a matching ] was incorrect if a ] may be consumed by a
[:class:]. The subsequent loop assumed that there must be a ].

Remove the initial check and make the loop cope with a missing ].

f504ca457f sh: Don't create bad parse result when postponing a bad substitution error.
An invalid substitution like ${var@} does not cause a parse error but is
stored in the intermediate representation, to be written as part of the
error message. If there is a CTL* byte in the stored part, this confuses
some code such as the code to skip an unused alternative such as in
${var-alternative}.

To keep things simple, do not store CTL* bytes.

5e4f40c860 sh: Avoid negative character values from $'\Uffffffff' etc.
The negative value was not expected and generated the low 8 bits as a byte,
which may be an invalid character encoding.

The final shift in creating the negative value was undefined as well.

Make the temporary variable unsigned to fix this.

02d6f9793e It has been long time that when doing 'ls -G /path/to/a/symlink', instead of
using the color of symbolic link, the color is determined by the link target.
This behavior was quite confusing.

Looking at the file history, it looks like that r203665 intends to fix this
but the issue was never actually fixed.

Fix this by not setting FTS_COMFOLLOW when color is requested like what was
done in r203665.

While here also improve the '-l' handling to not open(2) the source file as
it does not actually need the descriptor.

eb4e837132 cp: Remove fts sorting.
In an attempt to improve performance, cp reordered directories first
(although the comment says directories last). This is not effective with new
UFS layout policies.

The sorting reorders multiple arguments passed to cp, which may be
undesirable.

Additionally, the comparison function does not induce a total order. Per
POSIX, this causes undefined behaviour in qsort().

NetBSD removed the sorting in 2009.

On filesystems that return directory entries in hash/btree order, sorting by
d_fileno before statting improves performance on large directories. However,
this can only be implemented in fts(3).
