sbase/expand.1
FRIGN 692c11bf2b Add tablist support and a mandoc-manpage to expand(1)
and mark it as finished in the README.

This is another example showing how broken the GNU coreutils are:

$ echo -e "äää\tüüü\tööö" | gnu-expand -t "5,10,20"
äää    üüü    ööö
$ echo -e "äää\tüüü\tööö" | sbase-expand -t "5,10,20"
äää  üüü  ööö

This is due to the fact that they are still not UTF8-aware and
actually see "ä" as two single characters, expanding the "äää" with
4 spaces to a tab of length 10.
The correct way however is to expand the "äää" with 2 spaces to a
tab of length 5.
One can only imagine how this silently breaks a lot of code around
the world.
WHAT WERE THEY THINKING?
