9 years ago*: Switch to POSIX utmpx API
Bernhard Reutner-Fischer [Thu, 2 Apr 2015 21:03:46 +0000 (23:03 +0200)]
*: Switch to POSIX utmpx API

UTMP is SVID legacy, UTMPX is mandated by POSIX.

Glibc and uClibc have identical layout of UTMP and UTMPX, both of these
libc treat _PATH_UTMPX as _PATH_UTMP so from a user-perspective nothing
changes except the names of the API entrypoints.

modules which are getting loaded is  nls_cp437. While one module is being

the busybox version provides no way to suppress this behavior; the -n

it by default.

vi: fix reading of file after last line

If the :r command is used to read a file after the last line of the
buffer the last line of the buffer and the first line of the file
are joined.  An extra blank line appears at the end of the buffer.

   file 1
   file 1
   file 1file 2
   file 2
   file 2

~
~

The insertion point is normally at the start of the line following the
specified line.  When the specified line is the last one the next_line
function baulks at moving to the non-existent following line.
