  1. Avoid changing 'undolevels' when creating an undo break. 

    Setting the 'undolevels' option to any value has the side effect of
creating an undo break.  UltiSnips uses the below construct to create an
undo break with the goal of leaving 'undolevels' unmodified:

```
:let &undolevels = &undolevels
```

However, if a local 'undolevels' option has been set to a different
value than the global option, the assignment above has the unintended
effect of changing the global 'undolevels' value to the local value.

Use `&g:undolevels` to explicitly read and modify only the global option
value, avoiding undesired option changes.
