sage -fixoptional would rewrite doctest annotations # optional / # long / # needs (from #35779):

• use # optional only for optional features, # needs for standard features (infrastructure for standard status of features is added in Hide features (PR to migrated Trac ticket #34185) #35668)
• rewrite to use persistent (codeblock-scoped) annotations (from Implement persistent optional tag  #35779) when it reduces noise
• align at alignment points (>= column 88 for # needs; see https://gist.github.com/mkoeppe/d7c6224d780dbb9641a03c7ce4357e9e)
