In v.digit, you currently have to digitize as much line as you can in
the current zoom, then pan, digitize more line, pan, etc.

After leaving digitize line mode you can go into "move vertex" mode to
snap the two line ends together. Make sure you gave the two lines the
same category number.

It has been a long time wish to fix this & it should work a bit better
in the next generation digitization tool (wxPython GUI).


these bug reports sound hopeful:
