webrick: compile RE correctly for beginning and end match
Using ^ and $ in regexps means we can accidentally get fooled
by "%0a" in HTTP request paths being decoded to newline
characters. Use \A and \z to match beginning and end-of-string
respectively, instead.
Thanks to mame and hsbt for reporting.
* lib/webrick/httpserver.rb (MountTable#compile):
use \A and \z instead of ^ and $
* lib/webrick/httpserver.rb (MountTable#normalize): use \z instead of $
* test/webrick/test_httpserver.rb (test_cntrl_in_path): new test
