The notices have been changed to a more GNU look. Documentation
comments have been separated from the copyright header. I've tried to
keep all copyright notices intact. Some author contact details have
been updated.
I re-indented the source code using indent with the following options:
indent -kr -bad -bap -nut -i8 -l80 -psl -sob -ss -ncs
There are now _no_ tabs in the source files, and all indentation is
eight spaces. Lines are 80 characters long, and the procedure type is
on it's own line. Read the indent manual for more information about
what each option means.
Moved the struct buffer_s into the header file. Added more assert() calls
to better document the assumptions the functions make. Removed incorrect
code in remove_from_buffer() which was never actually called anyway.
