use null character as for loop delimiter

[Hunter Peress]

theres so many filenames out there that bring bash to its knees. 

suppose you have a directory full of ugly file names,  then with this
proposed feature,

for each in `ls | tr '\n' '\0'` ; do something ;done  would work.



currently, i like to      do stuff | tr '\n' '\0' | xargs -0 -i  
stuff '{}' stuff



find and xargs support it. so should bash add this feature
