Bug 27308: Skip blank lines when inserting new

The intent of the macro insert new function is to add a new field at the correct numerical place in the record. If you have a blank line while editing, however, the new line will be inserted at the blank line, rather than checking the rest of the record.

To test:
1 - Create a macro like
    new 690=‡aLOCAL SUBJECT
2 - Insert a blank line into your record somewhere before where the 690 should be inserted
3 - Run the macro
4 - Line is inserted before the blank line
5 - Apply patch
6 - Reload (ensure cache is cleared and JS files are reloaded)
7 - Remove the previously created field, but leave the blank
8 - Run the macro
9 - Field is created at correct position

I don't think we need to keep the original line as a comment.. this
patch simply cleans it up.
