tidy always being rebuild with --bless

[matthiaskrgr]

this works fine:

x.py test
x.py test

x.py test
x.py test --bless

this also works

x.py test --bless
x.py test --bless

this seems to rebuild tidy for the second invocation? as if --bless somehow modified tidy itself which then need to be rebuilt?

It's probably due to rewriting issues.txt with the same data. I hadn't considered the vagaries of incremental.
