less: fix botched attempt to use last column
Commit
1ecb996 attempted to make read_lines() use the last column of
the terminal (as re_wrap() did). There were two problems with this:
- The size of the buffer allocated for lines wasn't increased to allow
for the extra character.
- The test for width overflow was moved after the point where the
next character was added to the buffer. This caused a buffer overflow
in certain circumstances.
For example, if the line beyond the end of the display was wider than
the display read_lines() would initially read the partial line into a
buffer. When the user moved down read_lines() would be called again
to ensure the rest of the line was read. This would place the next
character in the partial line before checking for overflow.
This can be fixed by moving the test for overflow back to where it was
before commit
1ecb996 and changing the comparison to `>` rather than
`>=`.
There are two other places where buffers are created without allowing
for width+1 characters.

echo: make escape sequences depend on fancy mode
Currently when you disable fancy echo, escape sequences are hardcoded
enabled (e.g. as if you used `echo -e` all the time). The opposite
behavior is more desirable (always disable -e support) because:
* This seems to contradict the spirit of the kconfig help text (where
it says enable support for -n/-e flags), although you could say that
we aren't supporting the -e flag directly as `echo -e` will show the
-e flag.
* POSIX makes escape sequences optional, and even says they are there
only on XSI-conformant systems.
* It saves space (~100 bytes on x86_64).
* It makes things faster!
* It makes it behave more like bash where you need an explicit -e flag
in order for escape sequences to be interpreted.

by Herbert Xu says:
>The parsebackquote flag is only used in a test where it always has the
>value zero. So we can remove it altogether.
The first statement is incorrect: parsebackquote is non-zero when
backquotes (as opposed to $(...)) are used for command substitution.
It is possible for the test to be executed with parsebackquote != 0 in
that case.
The test is question checks whether quotes have been closed, raising
the error "unterminated quoted string" if they haven't. There seems
to be no good reason to allow unclosed quotes within backquotes. Bash,
hush and dash (after commit
503a0b8) all treat the following as an error:
XX=`"pwd`
whereas BusyBox ash doesn't. It just ignores the unclosed quote and
executes pwd.
So, parsebackquote should be removed but not for the reason stated.

libbb: Enable support for !CONFIG_MULTIUSER
Linux recently gained a new config option, CONFIG_MULTIUSER, that makes
support for non-root users optional. This results in a number of syscalls
being disabled: setuid, setregid, setgid, setreuid, setresuid, getresuid,
setresgid, getresgid, setgroups, getgroups, setfsuid, setfsgid, capget,
capset.
Currently a number of busybox applets, including login, struggle to run
when CONFIG_MULTIUSER is disabled. Even the root user is unable to login:

This patch adds code to make change_identity() a nop on single user
systems. It works by recognising the signature errno value (ENOSYS, due
to the system calls being disabled) and, to avoid security risks, only
deploys when the current uid and target uid is the same.
After the patch is applied any attempt to switch to a non-root user will
fail. Thus a badly configured userspace (for example, one that tries to
start a daemon as a non-root user when the kernel cannot support this)
will report errors as one would expect.
