#276: Osgeo4w.bat problem with setting root

-------------------+--------------------------------------------------------
 Osgeo4w.bat has a line in it to remove the trailing backslash from the
 auto-generated OSGEO4W_ROOT variable. Most of the time this works just
 fine, however if the root happens to be the top of a drive instead of a
 folder unexpected things can happen.

 The immediate fix is to REMark out the line, as shown below. It should be
 safe and have no functional repercussions.
 {{{
 rem Remove trailing backslash
 rem set OSGEO4W_ROOT=%OSGEO4W_ROOT:~0,-1%
 }}}

 The purpose of the line is largely cosmetic, it prevents a double
 backslash appearing in things like `PATH=%OSGEO4W_ROOT%\bin;` (becomes
 `PATH=C:\Osgeo4w\\bin;`). In testing Windows seems to ignore double
 slashes faithfully and completely.

 Without the fix in place, if osgeo4w_root is a drive letter (`X:`), then
 it become relative to whatever the current directory on the drive is
 instead of the absolute location.

 The next release of [wiki:pkg-shell] will have a fix.
