To avoid confusion (although readers may not require), even though I
explained "boring mechanical part" first and "refactoring", that was
purely for explanation.
In practice, I would expect that it would be easier to both do and
review if refactoring is done with the original name.
A function that will keep its name in the final result (e.g.
start_multi_file_filter()) will call a new and more generic helper
function. The new helper may start using the new name from the
get-go (e.g. subprocess_start()), but the data types it shares with
the original part of the code (e.g. 'struct cmd2process') may still
be using the original name.
And after completing "2 or more" refactoring would be a good place
to do the remaining "boring mechanical rename". IOW, the count
above could be
2 or more (refactoring) +
1 (boring mechanical part) +
1 (final movement)
and I didn't mean to say that you need to rename first. What we
want is "if you need to have a single large patch that cannot be
split, see if you can make it purely mechanical.", as a single large
patch that is _not_ mechanical conversion is the worst kind of patch
for reviewers.
