Fix uparse to deal explicitely with empty lines. |
|
|
|
Uparse accessed undefined elements if the input line was empty. This was |
|
harmless because the default branch of the switch led the control flow |
|
to the right place, however it could appear a bit obscure. Adding an |
|
extra test will not hurt performance and make the code easier to read. |
