“Catastrophic” repository “corruption”? This sounds very strongly like
an urban legend.
Perhaps some files had later to be fixed. But that shouldn't be out of
the realm of normal Mercurial commands (aka "edit file to fix endings,
then hg commit and hg push").

Well, the latter is a given, isn't it? ;)

Anyway, hgeol actually seems to include such a hook. I'll try to enable
it.
