You'll notice
Two path-normalizing helpers now accept relative paths, not just absolute ones
What
Two internal path-handling helper functions previously rejected any input that didn't start with a leading slash (/), returning null for relative paths. That restriction has been removed, so both functions now also process relative paths.
Why
This broadens where these helpers can be used, since they no longer fail outright on relative paths.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say which callers rely on these helpers or what effect processing relative paths has downstream.
