git-subtree-check fails if the directory is given with a trailing slash, eg: ``` > test/lint/git-subtree-check.sh src/univalue/ ERROR: src/univalue/ is not a subtree ``` Shell autocompletes will add the trailing slash when autofilling the path name, which will therefore cause the script to fail. Just ignore any trailing slash.
