Leah Rowe e9a910b33c config/git: import suckless sbase
i currently use the output of sha512sum in several
places of xbmk, which is a bit unreliable in case
output changes.

other cases where i use util outputs in variables
are probably reliable, because i'm using mostly
posix utilities in those.

to mitigate this, i now import suckless sbase, which
has a reasonable sha512sum implementation.

*every* binary it builds is being placed in build.list,
because i'll probably start using more of them.

for example, i may start modifying the "date"
implementation, adding the GNU-specific options that
i need as mentioned on init.sh

i'm importing it in util/ because the sha512sum
util is needed for verifying project sources, so
if sbase itself is a "project source", that means
we can into a chicken and egg bootstrapping problem.

this is sbase at revision:

.Sh NAME
.Nm cols
.Nd columnize output
.Sh SYNOPSIS
.Nm
.Op Fl c Ar num
.Op Ar file ...
.Sh DESCRIPTION
.Nm
reads each
.Ar file
in sequence and writes them to stdout, in as many vertical
columns as will fit in
.Ar num
character columns.
If no
.Ar file
is given,
.Nm
reads from stdin.
.Pp
By default
.Nm cols
tries to figure out the width of the output device.
If that fails, it defaults to 65 chars.
.Sh OPTIONS
.Bl -tag -width Ds
.It Fl c Ar num
Set maximum number of character columns to
.Ar num ,
unless input lines exceed this limit.
.El
.Sh ENVIRONMENT
.Bl -tag -width Ds
.It COLUMNS
The width of the output device.
.El
.Sh HISTORY
.Nm
is similar to
.Xr mc 1
in Plan 9. It was renamed to
.Nm
to avoid the name collision with the popular file manager
Midnight Commander.
.Sh CAVEATS
This implementation of
.Nm
assumes that each UTF-8 code point occupies one character cell,
and thus mishandles TAB characters (among others).
.Pp
.Nm
currently mangles files which contain embedded NULs.
