Two problems with the changeset comment field

[mueschel]

If I enter a comment for the changeset and then press enter, the editor:

a) does not commit the changeset, but tries to load new data and complains about a missing URL
b) If the changeset comment contains a special character like " only the part in front of this character is retained, the part after it is lost.

Would improve handling if these two issues could be fixed.

Done. Thanks for the report!
