Skip "ml_line_len" member of "struct memline".
Patch v8.1.0579 was not ported.
Problem: Using sign group names is inefficient.
Solution: Store group names in a hash table and use a reference to them.
Also remove unnecessary use of ":exe" from the tests. (Yegappan

Problem: Placing signs can be complicated.
Solution: Add functions for defining and placing signs. Introduce a group
