vi: stored search pattern applies to ':s'
...
The same stored search pattern applies to both search ('/') and
search/replace (':s') operations.
A search/replace operation with an empty "find" string (':s//abc/')
should use the last stored search pattern, if available, and issue an
error message if there is none.
If the "find" string is not empty it should replace the stored search
pattern.

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.

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:
