I most probably took GNU linebuffer.[hc] from the /lib directory of
some GNU *util distribution, but I do not remember which.  Hopefully,
there is a master copy somewhere for the GNU staff.

Both initbuffer() and freebuffer() receive, for their argument, an
already allocated `struct linebuffer'.  freebuffer() frees it.  So,
despite perfectly legal to pass a statically allocated variable to
initbuffer(), it is not legal to do so for freebuffer().  I feel it
would be more consistent if initbuffer() and freebuffer() could always
be used in pair.  One approach could be that freebuffer() does not
free its argument.  Another could be that initbuffer() has no argument
and returns a freshly allocated `struct linebuffer' structure.
