Feature Request: Allow customizing cursor jump behavior

[ColinKennedy]

If you have a file like

def foo():
    do_something()

And you edit

-def foo():
+def foot():
    do_something()

Then

def foot():
-    do_something()
+    do_blah()

Then

def foot():
-    do_blah()
+    foo_blah()

before.nvim records 3 changes, because the last 2 changes are on the same line. It'd be nice to be able to customize that behavior so same-line jumps are ignored and it just goes to the next position that is on a different file or line. And in this mode, the cursor always jumps to the first non-whitespace character instead of the exact column.

It'd probably be a good thing if these are 2 separately configurable options

• {["cursor_behavior"] = "exact" | "start_nonwhitespace"}
  • exact: go to the line + column
  • start_nonwhitespace: go to the first non-whitespace character
• {["skip_lines"] = "never" | "same_line_and_buffer"}
  • "never": don't skip any lines when doing jumps
  • "same_line_and_buffer": Skip the next jump if it's in the same line and buffer as the previous jump

To be honest it's trying to ignore same-line edits currently. Maybe I've missed some edge case, going to check. Thank you for a clear description!

You know I can't seem to reproduce it anymore. If it happens again I will let you know though!

Actually, now it might happen when you wrap around the history list, i.e. if the last and the first edits are in the same line. I will think how this could be solved, maybe deduplication logic can be improved further.
