I'm running bash 3.2.39(1)-release (under Ubuntu 8.04 (Hardy)
GNU/Linux). Neither bash.info or bash(1) documents parameter
expansion of the form:
${parameter+word}
This is different to ${parameter:+word}, is clearly implemented by
bash and is documented in the standard (The Open Group Base
Specifications Issue 6, IEEE Std 1003.1, 2004 Edition).
This may be useful:

Thanks for bash, it rocks... :-)
peace & happiness,
