Added ngx_filename_cmp() with "/" sorted to the left. This patch fixes incorrect handling of auto redirect in configurations like: location /0 { } location /a- { } location /a/ { proxy_pass ... } With previously used sorting, this resulted in the following locations tree (as "-" is less than "/"): "/a-" "/0" "/a/" and a request to "/a" didn't match "/a/" with auto_redirect, as it didn't traverse relevant tree node during lookup (it tested "/a-", then "/0", and then falled back to null location). To preserve locale use for non-ASCII characters on case-insensetive systems, libc's tolower() used.
