As per the discussion on IRC, sorry, for some reason I assumed we have the
metadata (including the commit message) in the converted patch. But of course,
we don't. Hence having rapply.sh commit the changes doesn't make much sense, in
the end. In fact it increases the risk that people push commits imported from
Rietveld with wrong commit message and author.

[Vasily Kuznetsov, 2017/08/25 18:52:14]

Done.

patchconv.py is executable. Specifying the interpreter is redundant.

[Vasily Kuznetsov, 2017/08/25 18:52:14]

Done.

+elif which -s patchconv; then
+    alias PATCHCONV=patchconv
+else
+    echo "Can't find patchconv in the PATH or in $BASEDIR."

[Sebastian Noack, 2017/08/25 16:40:38]

This error message and the `which ...` check above seems superfluous. Just fail
with the native error, you get when trying to call patchconv?

[Vasily Kuznetsov, 2017/08/25 18:52:14]

Done.
