Rename file names with spaces in them

[bob-fontana]

Description of Issue:

When traversing directories during mass operations, files with spaces always cause scripts to be overly convoluted (for F in ...; do...)

Details of Issue:

Because the input field separator is white space, a collection of file names with spaces cause the list of files to break each file name into separate "words" which become meaningless. Loops blow out, etc.. The workaround is to use the (find . -name '*.xxx' | while IFS= read -r -d x...). The flexibility of this construct is limited. It needs to go away.
