lineedit: fix matching of directories when searching PATH

2023-03-29T14:45:13+00:00

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. Signed-off-by: Ron Yorston Signed-off-by: Denys Vlasenko
