Shell auto-completion for "less" adds space after directory names

Binary package hint: less

Make sure a file /tmp/a.txt exists.

In a terminal, type "less /tm<TAB>". The expected result would be "less /tmp/", instead I see "less /tmp ", which effectively ruins the use of auto-completion as I manually have to remove the space and type a "/" (which with some keyboards is not as easy as with the English one).
