cmd hack to not move the cursor and a fix for recursive mapping

[Sam-programs]

this fixes =,$ and k mappings being broken (which i made sorry users)
and doesn't move the cursor on custom pairs with a cmd hack
more info:
#394

so yeah here is the new pr with more sane commits windwp
i doubt the test on line 82 of test_utils is gonna pass tho it's probably safe to remove

Can you only change normal to normal!
I can't use nvim_api win_set_cursor it will break another thing with undo.

[Sam-programs]

i don't notice any changes to undo blocks using set_cursor
i reverted back to the first commit that doesn't have the cmd hack
lets merge this to fix the issues the users are having and if you would like we can discuss the cmd hack later as it seems harmless

thank
