7180d9ed86 examples/udhcp/simple.script: fix resolv.conf update if it is a dangling symlink
If /etc/resolv.conf is a symlink to a tmpfs and the actual file does not
already exist, "readlink -f" will not detect it as symlink. Explicitely check
for that condition before and touch the file, making the other code work as
intended.

1e474d3d93 service examples: if iface do not exist, retry upping it
I've had a case of a machine where eth0 was appearing a bit later
after the boot, and appearing _downed_. ifplugd then fails to detect
"link up". Thus, depending on how service startup
("ip link set dev eth0 up") races with driver initialization,
ethernet randomly fails to initialize on boot.

a2fd1aaf86 vi: allow manual screen update if SIGWINCH isn't supported
On platforms that don't support SIGWINCH vi can be configured
with FEATURE_VI_USE_SIGNALS disabled and FEATURE_VI_WIN_RESIZE
enabled.  This allows the user to force an update with ^L when
the screen is resized.

However, because the SIGWINCH handler hasn't run the virtual
screen buffer won't have been updated and the display becomes
corrupted.  Fix this by calling new_screen() if necessary.

3c6f3336e1 man: don't skip default path which appears in config file
If the MANPATH environment variable isn't set a provisional default
path of /usr/man is placed in man_path_list.  This is only used if a
configuration file doesn't contain an alternative path.

If a configuration file lists the default path first:

   MANPATH /usr/man:/usr/share/man

add_MANPATH() sees that the default entry is already present and skips
it.  As a result man_path_list only contains the second and subsequent
components of the configured MANPATH.

In such cases the path should not be skipped.
