Subject: [PATCH] Return with previous exit code in Bash prompt function (#199)

asdf-java prepends to `$PROMPT_COMMAND`, thus swallowing up the
previous command's exit code (normally the command the user
invoked). This is troublesome if the exit code is used in the
user's own prompt command, for example to output a different
prompt.
