			This is for the sake of the new rST generator (the "transmogrifier") so
we can advance multiple lines on occasion while keeping the
generated<-->source mappings accurate.
next_line now simply takes an optional n parameter which chooses the
number of lines to advance.
The next patch will use this when converting section syntax in free-form
documentation to more traditional rST section header syntax, which does
not always line up 1:1 for line counts.
For example:
```
 ##
 # = Section     <-- Info is pointing here, "L1"
 #
 # Lorem Ipsum
 ##
```
would be transformed to rST as:
```
=======        <-- L1
Section        <-- L1
=======        <-- L1
               <-- L2
Lorem Ipsum    <-- L3
```
After consuming the single "Section" line from the source, we want to
advance the source pointer to the next non-empty line which requires
jumping by more than one line.
