Workout zero repeat crash

[gerhardol]

Zero repeat steps will never finish, #568

Still allow 0 repeats, can be used to skip parts 'dynamically'

@gerhardol is this the right PR? We need really 141 commits and change 253 files to fix this bug, dropping FROYO as part of the PR, etc? Or was it a typo and you pushed a branch that was supposed to do something else, which should be merged separately?

[gerhardol]

This PR is based on #624 that is based on #524 So only the last commit is for this PR, the two before for #624 I cannot test in any other way...

[davidedelvento]

Ah, I see. Can't you merge the other two PRs first and do this one later, just to make things easier to follow?

From a stylistic point of view, why commenting out sections of code instead of deleting them?

Commenting out:
I do that when there are better ways to do a change. Could hav added comments too

The Asserts are situations that should not occur, but do. Not new.

I could make a new PR sure, but I believe you will see only the relevant commits when the preceeding PRs are merged.
PRs that build on eachother are harder to follow, but is better than big PRs. If the PRs cannot be separate like this that builds on previous, I believe it is fine.

Alright, thanks for taking the time to explain.
