Sometimes we have a short base64 encoded string we need todecode.
This function makes it simpler.
License change of the test module justified because I am the single
author of the code.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
