busybox's chpst first switches user/group and then tries to call nice().
Once the root priviledges are dropped, process priority can only be lowered.
So negative nice values don't work anymore.
Upstream version of chpst correctly calls nice() before switching user.

Along with it, there are other changes
- Check for uppercase X is removed as the expression will be always false and
:X itself is another totally different command in standard vim
- The status line will show number of written lines instead of lines requested
by the colon command. This is also how the standard vim is doing, though
the difference is that '!' has to be explicitly specified in vim to allow
partial writes

... when gzip is selected but not gunzip nor zcat, or when bzip2 is
selected but not bunzip2 nor bzcat.
This regression is introduced in b130f9f758
("Allow 'gzip -d' and 'bzip2 -d' without gunzip or bunzip2")

- modprobe can indirectly benefit from FEATURE_2_4_MODULES and
FEATURE_INSMOD_TRY_MAP options.
- The position of config FEATURE_INSMOD_TRY_MMAP prevented some other
config options from indenting under FEATURE_2_4_MODULES. Reorder to
fix this.
- FEATURE_MODPROBE_SMALL_CHECK_ALREADY_LOADED is now moved to
Config.src under "Common options" section. (I wished to edit this
config so that it also work with "big" modutils, but it's not done at
the moment. Sorry.)

- The modprobe-small implementation of rmmod no longer chdir's to
"/lib/modules/`uname -r`" as it was not necessary for rmmod's
operation. (And it no longer need to die if such modules directory
doesn't exist.)
- Configs DEFAULT_MODULES_DIR and DEFAULT_DEPMOD_FILE no longer depend
on MODPROBE_SMALL as the latter may not enable depmod or modprobe
that requires these configs.
- Clarify DEFAULT_DEPMOD_FILE's description regarding the ".bb" name
suffix.

Allow module options on command line to be disabled on "big" modutils.
Config FEATURE_MODPROBE_SMALL_OPTIONS_ON_CMDLINE is renamed to
FEATURE_CMDLINE_MODULE_OPTIONS and no longer depends on !MODPROBE_SMALL
(I'm not sure if disabling this is useful on "big" modutils, but at
least the macro can serve as a marker and ensure both implementations
of same feature have consistent behavior.)

When using musl libc glob() a very long string can cause glob() to fail,
which leads to an out of memory error being raised by ash.
This can happen easily if a very long quoted string contains *, even
though no glob expansion should ever be performed on it (since it's
quoted).
Fix this by properly parsing control characters and escaping and only
accept unquoted metacharacters. While we're at it, unify this check for
libc and built-in glob expansion

module.aliases and module.symbols files have no use in modprobe-small
implementation. So FEATURE_MODUTILS_ALIAS and FEATURE_MODUTILS_SYMBOLS
will depend on !MODPROBE_SMALL.
The try_to_mmap_module() function is not called in modprobe-small.c,
so I will let FEATURE_INSMOD_TRY_MMAP depend on !MODPROBE_SMALL for
now.

Anonymous ftpd login is useful even when ftpd authentication feature
is enabled. Anonymous logins provide simple password-less connection
for FTP clients.
To allow password-less connection user command line option '-a USER' is
added. This option specifies the system user to use when
'anonymous' username is given in USER command. No password is required
in this case.
