Delete bz2 file when compression fails

[nemobis]

Using 2.3, when #14 happens, the bz2 file is not deleted:

$ lbzip2 beic-010.10.tar
lbzip2: skipping "beic-010.10.tar": open("beic-010.10.tar.bz2"): File exists
$ ls -lh beic-010.10*
-rw-rw-r-- 1 fondazione fondazione 4,1G giu 20 11:22 beic-010.10.tar
-rw------- 1 fondazione fondazione  25M giu 20 11:38 beic-010.10.tar.bz2

Thank you for the report, but I'm afraid that this won't be fixed.

Once started, compression can fail due to several different reasons - normal and abnormal. Normal reasons include I/O error, out of disk space, insufficient memory etc. In all these cases output file should be removed upon exit, as expected.

However assertion error (such as #14) means a bug in the code. When such abnormal condition occurs, the program is aborted immediately without any cleanup and core is dumped to allow debugging. This is by design and it won't be changed. The right thing is fixing the original bug, not working it around.
