Hi,
As you may have noticed, when cursor is in the "virtual space" (beyond eoln), our status bar always shows the last "real" column. This small patch adds a new %v (and %V) format specification, which displays a "virtual" column number, as if the line extends to the cursor position. I haven't included sci_get_cursor_virtual_space() is the plugin interface for now.
Since the virtual position normally requires 3 SSM()-s, and is less likely to be used than the line and column, I placed the calls into add_statusbar_statistics() instead of ui_update_statusbar().
