shaver%netscape.com 24299cc8ca - Portions of nsIFile and nsIDirectoryEnumerator implementations for Unix.
- Various missing-newline-at-end-of-file fixes from Andrew Taylor
  <Andrew.Taylor@cal.montage.ca>.
- Fixed case in nsIDirectoryEnumerator.idl
- Added |normalize()|, |truncate()| and |target|, |isSpecial()| to nsIFile.idl
- Changed |isExists()| to |exists()|, |fileName| to |leafName|, |isEqual()| to
  |equals| and added |in boolean recur| to |isContainedIn()|.
- Corrected widespread misspelling of |NS_ERROR_FILE_UNRECOGNIZED_PATH|.
- Partially updated Windows code to track changes.
