[BusyBox] Trivial whitespace cleanup

[Larry Doolittle]

Erik -

Could you run this script on your source tree?
On my copy, it finds 18 C source files (*.[ch]) with
trailing whitespace, all useless.  The script is much
shorter and (I hope) less likely to get corrupted
by mailers and web gateways than the patch is.
The whitespace between [ ]'s are both supposed to
be <space><tab>.

# Get rid of trailing spaces and tabs in C source code.
# Don't mess up the time stamps of files that don't need changing.
# Show progress by listing the files that are changed.

for f in `find . -name "*.[ch]"`; do
    if grep "[  ]$" $f >/dev/null; then
        echo $f
        sed -e 's/[     ]*$//' <$f >temp.$$
        mv temp.$$ $f
    fi
done
