# affect ssh either, as it ignores the environment variable entirely.

# However, a useful trick is pointing SVN_SSH to a program that doesn't exist,
# resulting in svn skipping ssh entirely. Alternatives like

// if the function returns a non-nil error, WalkDir stops entirely and
// returns that error.
//
// The err argument reports an error related to path, signaling that
// [WalkDir] will not walk into that directory. The function can decide how
// to handle that error; as described earlier, returning the error will
// cause WalkDir to stop walking the entire tree.
