Many tools strip trailing whitespaces by default, so after editing a file with
whitespace errors we end up with a bunch of unrelated hunks that need to be
reverted locally.
This could be fixed by configuring each tool to not do this (at least for the
barrier repo), or, simpler, we just sed the problem away and make barrier
whitespace-compliant.
sed commands run:
sed -i 's/[ \t]\+$//' **/*.(cpp|h) **/*CMakeLists.txt
Verified with git diff --ignore-space-change, this shows the empty diff.
It's probably better to wait until the buffer is sent, rather than
waiting until its empty. To test the output it has to be sent, but
because of timing, it may be emptied at any point.
