got around to this. new repo is here: https://github.com/gitrj95/trail.el

renamed from breadcrumbs to trail, as per joao's suggestion, and changed the 
semantics quite a bit. i had some questions:

-   i'm supporting "middle" truncation of the file path strings. i couldn't 
find this in emacs libs, but for this purpose, i found truncation at the suffix 
or prefix less useful than truncation in the middle. ie, i want to know the 
file name and extension almost always and the root directory (especially in a 
code context) almost always
-   i'm using markers to track relative positions instead of absolute 
positions. i found that, especially in the code context, i wanted the 
trail-mark to "know" that i've added code before it, but still point to the 
function prototype i marked before instead of sliding. markers don't seem to be 
persistable, so i had the absolute positions of the markers stored in the ring 
that can be persisted, but default to corresponding markers in an associated, 
private ring if those exist. on hook for buffer close, the absolute positions 
are updated with the marker details. this seems like a fairly common thing to 
want to do, so i'd hope that i didn't reinvent the wheel. again, i couldn't 
find anything

also:

-   checkdoc passes
-   tested on emacs 27, 28, and 29

let me know if you have any questions, and please send over the fsf copyright 
agreement when you have the chance

looking forward
