Scrap readrune(), introducing fgetrune()
...
Interface as proposed by cls, but internally rewritten after a few
considerations.
The code is much shorter and to the point, aligning itself with other
standard functions. It should also be much faster, which is not bad.

tail: Add rudimentary support to detect file truncation
...
We cannot in general detect that truncation happened. At the moment
we use a heuristic to compare the file size before and after a write
happened. If the new file size is smaller than the old, we correctly
handle truncation and dump the entire file to stdout.
If it so happened that the new size is larger or equal to the old size
after the file had been truncated without any reads in between, we will
assume the data was appended to the file.
There is no known way around this other than using inotify or kevent
which is outside the scope of sbase.
