libbb: revent previous version of "concurrent history updating"
...
and replace it with one which does not "snoop" history written
by others. (1) it is what bug 185 needs, and (2) it is less bloaty:

libbb: make history saving/loading concurrent-safe
...
* all history writers always append (not overwrite) history files
* they reload history if they detect that file length has changed since last
write
* they trim history file only when it grows 4 times longer than MAXLINES
* they do this atomically by creating new file and renaming it to old
Unfortunately, this comes at a price:
