Subject: utils: add proper handling of "/" special case in uh_path_match()
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fuhttpd.git;a=commitdiff_plain;h=1628fa4b34aa143187353f81e8001b9a15286bda

utils: add proper handling of "/" special case in uh_path_match()

The special prefix of "/" should match any url by definition but the final
assertion which ensures that the matched prefix ends in '\0' or '/' is causing
matches against the "/" prefix to fail.

Add some extra code to handle this special case to implemented the expected
behaviour.
