I would not try to automatically "fix" revlib revisions by default. Think
about incompatible revlib formats as something related (tla 1.2.1 creates
revlib in the format unknown for tla 1.2). I prefer to get an error of
possible corruption, with suggestion to run library-remove bad--revision.

I support this solution. Still, I'd like to get a warning when inode 
signatures are recalculated, as a signal of a possibly larger problem.

Additionally, I support having ~/.arch-params options that override these
defaults, i.e. allow automatical recreation of corrupted revlib trees, or
maybe suppress warnings when recalculating inode signatures.
