%Docstring
 | 
						|
Attempts to commit any changes to disk.  Returns the result of the attempt.
 | 
						|
If a commit fails, the in-memory changes are left alone.
 | 
						|
 | 
						|
This allows editing to continue if the commit failed on e.g. a
 | 
						|
disallowed value in a Postgres database - the user can re-edit and try
 | 
						|
again.
 | 
						|
 | 
						|
The commits occur in distinct stages,
 | 
						|
(add attributes, add features, change attribute values, change
 | 
						|
geometries, delete features, delete attributes)
 | 
						|
so if a stage fails, it's difficult to roll back cleanly.
 | 
						|
Therefore any error message also includes which stage failed so
 | 
						|
that the user has some chance of repairing the damage cleanly.
