Michael Forney a944b682a6 sort: Fix line comparison when col buffer contains data from longer line
I'm not sure if there are other implications of this or not, but
the issue is that columns() uses len to store the allocated buffer
size, but linecmp() compares up to len bytes. If those trailing
bytes do not match, the line is considered not matching, even though
the relevant parts of the buffer do match.

To resolve this, also keep track of column capacity. Additionally,
since there is no reason to keep the existing data when resizing,
just use free and emalloc rather than erealloc.

The simplest case I could reduce it to is this:

if [ "$(printf '%s\n' a a xxb xxc | ./sort -u)" = "$(printf '%s\n' a xxb xxc)" ] ; then
	echo pass
else
	echo fail
fi

sbase - suckless unix tools
===========================

sbase  is a  collection of  unix  tools that  are inherently  portable
across UNIX and UNIX-like systems.

The following tools are implemented:

'#'  -> UTF-8 support, '=' -> Implicit UTF-8 support, '*' -> Finished,
'|'  -> Audited,       'o' -> POSIX 2013 compliant,   'x' -> Non-POSIX,
'0'  -> NUL handling,  '()' -> Petty flag

The  complement of  sbase  is  ubase[1] which  is  Linux-specific  and
provides all  the non-portable tools.   Together they are  intended to
form a base system similar to busybox but much smaller and suckless.

Building
--------

To  build sbase,  simply  type  make.  You  may  have  to fiddle  with
config.mk depending on your system.

You  can  also  build  sbase-box,  which  generates  a  single  binary
containing  all  the  required  tools.    You  can  then  symlink  the
individual tools to sbase-box or run: make sbase-box-install

Ideally you will  want to statically link sbase.  If  you are on Linux
we recommend using musl-libc[2].

Portability
-----------

sbase has been  compiled on a variety of  different operating systems,
including Linux, *BSD, OSX, Haiku, Solaris, SCO OpenServer and others.

Various combinations of operating  systems and architectures have also
been built.

You can build sbase with gcc, clang, tcc, nwcc and pcc.
