There are strange people who make such links (kindof urlencoded?):
[[Második világháború#Partrasz.C3.A1ll.C3.A1s Szic.C3.ADli.C3.A1ban

The crash on header comments issue is now resolved.
Regarding the removal of entire sections not being a cosmetic change,
have a look at the comments on the original task where this was
introduced and if you still think that it should not be part of CC
toolkit, please consider leaving a comment there, reopening the the
task, or creating a new one. I guess we could also make it an
opt-in/opt-out option via user-config.py.
