lineedit: fix matching of directories when searching PATH

Commit 8baa643a3 (lineedit: match local directories when searching
PATH) included subdirectories of the current directory in the search
when tab-completing commands.

Unfortunately a short time later commit 1d180cd74 (lineedit: use
strncmp instead of is_prefixed_with (we know the length)) broke
this feature by returning an incorrect length for the array of paths.

Fix the length and reinstate matching of subdirectories.
