[PATCH v6 0/6] Handling of in-tree symlinks for absolute paths
The amount of tweaks seemed deserving of a reroll, so here it is:
* Added your test Junio, with what I figured was an appropriate commit
message describing the user-visible effect (to git-add since I think it's the
simplest to explain), the commit message for the second commit has been
reduced somewhat, to not duplicate the message completely.
* Duplicated quite a bit of the explanation from this first commit into
the last commit, in order to be more obvious about the issue it fixes, I'm
not sure if it's a bit too much?
* Reworded the last commit to not mention the full-path special case, and
replaced all occurences of in-repo with "inside work tree" or similar.
* Content-wise compared to 'pu' I've tweaked a few comments, un-inlined and
added the wtlen <= len check (and the ls-files test is new of course):
