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.
