[svn-r11652] Purpose:
Improvement

Description:
The copyright notice of some files may contain some white spaces such
as tabs, trailing blanks and \r (common in Windows files).  Diff will
flag them as not matching.  Could not just use -b or -w of diff because
it will ignore embedded spaces and could not handle \r anyway.

Solution:
Added a RINSE function will remove all \r and trailing spaces and
expand tabs to proper number of spaces.  Now, diff can compare without
worry of cosmetic white spaces.

Platforms tested:
heping, applying on a Windows/copy_hdf.bat file.
