9468ea06d2 lsattr,chattr: do not open e.g. device files unless asked directly; do not follow links 
Add O_NOFOLLOW (and O_NOCTTY for good measure) to open calls like e2fsprogs does.

In lsattr, when recursing, operate only on regular files, symlinks, and directories.
(Otherwise, "lsattr /dev" can e.g. open a watchdog device... not good).

At this time, looks like chattr/lsattr can't operate on symlink inodes -
ioctls do not work on open(O_PATH | O_NOFOLLOW) fds.

51358757c7 vi: fix backward search with GNU regex 
With FEATURE_VI_REGEX_SEARCH enabled backward searches don't work.
This is problematic on distros that enable regexes, such as Tiny
Core Linux and Fedora.

When calling GNU re_search() with a negative range parameter
(indicating a backward search) the start offset must be set to
the end of the area being searched.

The return value of re_search() is the offset of the matched pattern
from the start of the area being searched.  For a successful search
(positive return value) char_search() can return the pointer to
the start of the area plus the offset.

FEATURE_VI_REGEX_SEARCH isn't enabled by default but when it is:

9c291f2cc0 taskset: fix for PID longer than 12 chars 
Should we validate that PID is a number for "taskset -ap PID"?
We don't actually need it, and pathological input like
"../../DIR_WITH_LOTS_OF_PIDS" can only cause "taskset"ing
of many pids. Which is something user can do anyway.
