exfalso: problem with dotted path element on startup

exfalso /a/directory works as expected and show the content of /a/directory

If i use a path with an hidden directory (dotted name) the path is cut before the dotted element,
e.g.:

exfalso /a/.dotted/directory shows the content of /a/ and not of the subdirectory

Problem is reproducible with the following versions:
