FRIGN 51390a3c51 Audit sort(1) and mark it as finished
1) Remove the function prototypes. No need for them, as the
   functions are ordered.
2) Add fieldseplen, so the length of the field-separator is not
   calculated nearly each time skipcolumn() is called.
3) rename next_col to skip_to_next_col so the purpose is clear,
   also reorder the conditional accordingly.
4) Put parentheses around certain ternary expressions.
5) BUGFIX: Don't just exit() in check(), but make it return something,
   so we can cleanly fshut() everything.
6) OFF-POSIX: Posix for no apparent reason does not allow more than
   one file when the -c or -C flags are given.
   This can be problematic when you want to check multiple files.
   With the change 5), rewriting check() to return a value, I went
   off-posix after discussing this with Dimitris to just allow
   arbitrary numbers of files. Obviously, this does not break scripts
   and is convenient for everybody who wants to quickly check a big
   amount of files.
   As soon as 1 file is "unsorted", the return value is 1, as expected.
   For convenience reasons, check()'s warning now includes the filename.
7) BUGFIX: Set ret to 2 instead of 1 when the fshut(fp, *argv) fails.
8) BUGFIX: Don't forget to fshut stderr at the end. This would improperly
   return 1 in the following case:
   $ sort -c unsorted_file 2> /dev/full
9) Other style changes, line length, empty line before return.

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,
'()' -> 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.
