While i'm against whitespace damaged files or patches since my very first patch, and don't like brain damaged programmer's tools called text editors, i also want to encourage UNIX-way of using userspace.
Of course, i might be wrong and foolish. Anyway, what i'm trying to do is not to become new generation of Visual Perl#(R) implemented in Java(R) using XML with userspace, that suck. Many things in XXI century still can be done by tools founded 20-30 years ago. Why not try to? Here is script proposal and test case, just for interested parties. -- -o--=O`C info emacs : faq #oo'L O info make : not found <___=E M man gcc : not found
clean-whitespace.sh
Description: Bourne shell script
# last spaces must NOT be striped to two tabs
tabspace spaces tab spaces tab
# trailing tabs mixed with spaces
2x8 spaces, must be 2xtabs
tab spaces tab, bust be 2 tabs
# more trailing whitespace

The return value is zero for success, else a negative errno. It should
be checked, since the get/set calls don't have error returns and since
misconfiguration is possible. (These calls could sleep.)
