The output of line info in the line.log file now contains the

character the cursor is over. This corresponds to the 'a' character
before the '|' character below:

>0x78898a94340 b^0x7889632b320 f.0x7889632b340 3 3       a|abc

Previously it would not have been shown:

>0x78898a94340 b^0x7889632b320 f.0x7889632b340 3 3       |abc

Also, a fake new-line character is shown with '-' before the '|' char.

>0x78898a94340 b^0x7889632b320 f.0x7889632b340 3 3       -|
