Summary:                    httpd -d returns incorrect result if URL contains
%2f ('/')
Description: 
Bug was introduced in revision 12978
(http://www.busybox.net/cgi-bin/viewcvs.cgi?rev=12978&view=rev).

+	if(value1 == '/' || value1 == 0)
+		return orig+1;

This returns one more than the string pointer provided as an argument.
While this is used, presumably for a good reason, in the web server, this
results in incorrect decoding when using "httpd -d" to URL-decode a
string, i.e. the first character is dropped and translation is suspended.

Can be reproduced like this:
 httpd -d 'http://foo.bar.net/cgi-bin/fubar?fubar=foo%2fbar%2cfu'
Returns:
 ttp://foo.bar.net/cgi-bin/fubar?fubar=foo%2fbar%2cfu
Should return:
 http://foo.bar.net/cgi-bin/fubar?fubar=foo/bar,fu
