Tom Rhodes 33ffdd8115 Don't truncate the output file before making sure that we can
read at least 1 byte from the input file without problems.  This
fixes a bug in uncompress(1) that causes the accidental removal
of files that happen to have the same name as the output file,
even when the uncompression fails and is aborted, i.e.:

$ echo hello world > hello
$ touch hello.Z
$ ls -l hello*
-rw-rw-r--  1 giorgos  giorgos  12 Jun 14 13:33 hello
-rw-rw-r--  1 giorgos  giorgos   0 Jun 14 13:33 hello.Z
$ ./uncompress -f hello
uncompress: hello.Z: Inappropriate file type or format
$ ls -l hello*
-rw-rw-r--  1 giorgos  giorgos  0 Jun 14 13:33 hello.Z
