Puppet templates are processed on the master to produce a single file, then that whole file is transported to wherever the manifest says it should go. There is no way to after the fact adapt it to whatever file may be in the target location already. On the other hand, you can determine in advance what is in the target file and communicate it to Puppet via a custom fact. Then your template can use the fact value to create whatever the output is that you want. Overall, however, what you are asking runs against Puppet's grain. Why shouldn't Puppet know in advance whether line2 should be present, and if so, what it should contain? It is usually better to tell Puppet how a node should be configured than to try to make it adapt to how the node is already configured. If you're talking about managing a file that is also dynamically modified by some other agent then you are asking for trouble. This whole discussion has been rather abstract, however. If you can be more specific about what you want to do then we may be able to offer better advice and / or alternatives.
