improving suggestions when copying into the editor

[psmits1567]

We have discussed to mark blancs in a string, until now that is not improved. This causes unnessesary errors when copying a suggestion into the editor. This can simply be prevented by modifying the copy function
How to reproduce.

1. Find a string without a blanc at the beginning or end
2. Find a suggestion that begins or ends with a blanc
3. Copy that suggestion
4. Save it, wich will cause an error
   If the copy suggestion has a checking/correction function which removes or adds blancs, this error will be prevented.
