tree-wide: use strv_isempty() instead of strv_length() == 0 It's a lot faster in many cases, since it's O(1) rather than O(n). 2017-11-29 14:40:22 +03:00			`@@`

coccinelle: beef up isempty() checks (#7729) With these additions, coccinelle finds everything fixed by the first commit in PR #7695. In order not to needlessly conflict with that PR this PR won't include those fixes, but only the coccinelle changes to detect them automatically in the future. 2017-12-23 10:47:55 +03:00			`- strv_length(s) <= 0`
