3.2.3(5)-release

QUIT BEING LAZY, and test the experimental release before asking your 
question.  If more people would give positive feedback stating things 
like "hey - bash-3.1-9 still has a bug that I verified was fixed in bash-3.2.3-
5, and I haven't seen any regressions when using the experimental version", 
rather than asking rhetorical questions like "I know of this bug in 3.1, can 
someone else be bothered to check if it is fixed in 3.2?", I would be more 
inclined to promote bash-3.2.3-5 to current.
</gripe>

As it is, this week has already turned up two reports of unrelated issues that 
both fall in this category - something unrelated to cygwin that is broken in 
upstream 3.1 but fixed in upstream 3.2 - and zero reports of something broken 
in 3.2.3-5, so I'm already quite close to calling 3.2.3-5 good enough to 
promote.  The only reason I express so much reluctance is that bash is so 
fundamental to a large chunk of cygwin operation, and I was recently burned by 
the backlash of my \r handling changes being promoted to current without enough 
prior testing while it was in the experimental phase.
