2022-10-29strftime/wcsftime: use STRLEN, not strlenCorinna Vinschen1-1/+1
Commit 737e2004a3bb accidentally introduced a call to strlen in code used with wide character strings in case of wcsftime. Use STRLEN instead. Fixes: 737e2004a3bb ("strftime.c(__strftime): add %q, %v, tests; tweak %Z doc") Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
