Patch Level: 32

Description:
Sometimes .bash_history-XXXXX.tmp file remains present in $HOME directory.

Both ~/.bash_history and ~.bash_history-XXXXX.tmp are 65536 lines long, 
as specified by $HISTFILESIZE.
~/.bash_history-XXXXX.tmp contain older commands and doesn't contain 
more recent commands, as expected.

After manual removal of ~/.bash_history-XXXXX.tmp after some time new 
tmp file emerges.
