I think I did tests and simply removing the \ in this case will comment
out the rest of the line after the #, IIRC we would have to enclose it
in '', like

PYTHON_EXT_SRCS := $(shell grep -v '^\#' util/python-ext-sources)

But then if it works as-is, why pollute the patch? :-)

In general the less lines you touch in a patch, the better, don't fix
what isn't broken, helps reviewing, etc. :-)
