Iceberg - Merging when there are changes in the working copy

IceCommitish>>#validateCanMerge has the warning: ''Experimental Feature: merge when there is a dirty working copy. Could cause a loss of your local changes. Please commit before merge.''. Are there some known situations when code can be lost?

I'm asking because in releaser (https://github.com/feenkcom/gtoolkit-releaser) we want to switch (not checkout) from the `master` branch to the `release` branch and then merge `master` into `release` running into the above warning.

Switching to `release` branch, does a checkout at the git level, leaving the image code the same. Hence, the packages that have changed will be marked as dirty.  So there aren't manual changes just changes caused by switching to a different branch.

Cheers,

Andrei
