When this function is passed a path with a trailing slash, it runs right over the end of that path. Let's fix this. Co-authored-by: Alexandr Miloslavskiy <[email protected]> Signed-off-by: Johannes Schindelin <[email protected]>

Inspired by gitgitgadget#414, this is a minimal fix for the issue that
needs_hiding()runs right outside the buffer when being passed a path with a trailing slash.The patch in gitgitgadget#414 does too many things: it not only fixes the bug, but rewrites a large part of the function. This late in the -rc phase leading up to v2.24.0, I am not willing to risk such a rewrite.
