If someone wants to maintain this, that's fine with me, although adding
another file to remember to update doesn't seem ideal.
Another possibility that doesn't require a separate file is to state at the
end of a truncated list something like "Older entries can be found in
set.mm version of <date>, <GitHub download URL>". You can build the full
list by following the links until there is no "Older entries..." line.
(The date provides a backup in case the GitHub link stops working. If
there is concern about availability of very old versions, the full list
could be refreshed every now and then in a special commit.)
Off and on in the past, I've thought about truncating the label change list
since we can always go back to historical versions. One reason I didn't do
it was that the list represented a relatively small part of set.mm and it
didn't seem like an urgent matter. The current stats are:
Size of label change list: 598kB, or 1.4% of set.mm size
Lines in label change list: 12350, or 1.7% of set.mm line count
Number of lines with "moved": 3459, or 28% of label change list lines
Still, I agree some kind of truncation would be less clutter in the set.mm
header section.
