Emacs Defect. file-relative-name fail on some MS Windows Styled Path
file-relative-name doesn't work on MS Windows style path when the
drive letter is capitalized.
(file-relative-name "C:/Users/web/xyz.html" "C:/Users/web/") ; returns
"C:/Users/web/xyz.html"
(file-relative-name "c:/Users/web/xyz.html" "c:/Users/web/") ; returns
"xyz.html"
(file-relative-name "/Users/web/xyz.html" "/Users/web/") ; returns
"xyz.html"
GNU Emacs 24.1.1 (i386-mingw-nt6.1.7601) of 2012-06-10 on MARVIN
