Bug in argument processing in bash-2.04

[Govind Kamat]

There appears to be a bug in the argument processing mechanism of 
bash, which seems to have been introduced recently.  The previous 
version I used, 1.14 works correctly as do ksh, Solaris sh and others. 

$ echo a b | xargs bash echo-args
:a b:

whereas, the output should be:
:a:
:b:


The file "echo-args" contains:

for i in "${@-}"; do echo :$i:; done
