I just discovered the following "interesting" behaviour in the
version of HDB uucp shipped with AT&T's SysVr3.2:
If you uucp a new copy of an existing file and (1) the new file
is shorter than the old one and (2) the directory containing the
file is not writable by uucp, the file is not truncated to the
new length but the new contents overwrite the corresponding portion
of the existing file.
