path2url DOS/Win32 patch

[Jason Hood]

I have attached a patch for the DOS and Win32 ports of the
htags-refkit.  It is necessary for htags_load_filemap() to
open the file in binary mode, otherwise the return value
of read() will not agree with the file size, causing the
function to fail.  I also just noticed a typo in the
leading comments: "requried" should be "required".

Jason.
