After testing a bit around with quotation marks, I made the following changes to osgeo4w.bat:

@echo off
rem Root OSGEO4W home dir to the same directory this script exists in
set OSGEO4W_ROOT=%~dp0
rem Convert double backslashes to single
set OSGEO4W_ROOT=%OSGEO4W_ROOT:\\\\=\\%
echo. & echo OSGEO4W home is %OSGEO4W_ROOT% & echo.

set _path=%OSGEO4W_ROOT%bin
call "%OSGEO4W_ROOT%bin\\addpath.bat" _path
set _path=

rem Add application-specific environment settings
for %%f in ("%OSGEO4W_ROOT%\\etc\\ini\\*.bat") do call "%%f" 

rem List available o4w programs
rem but only if osgeo4w called without parameters
rem if [%1]==[] call o-help
@echo on

@if [%1]==[] (cmd.exe /k o-help) else (cmd /c "%*")

and for o-help.bat:

@echo off
:: Osgeo4w Quick Help -- report available executables in o4w bin directory

  echo.                   -={ OSGeo4W Shell Commands }=-
  if ["%OSGEO4W_ROOT%"]==[] goto :NoEnv

      rem Generate executables list
      pushd %OSGEO4W_ROOT%\\bin
      echo.                     > "%temp%\\o-help-list.txt" 
      dir /d *.exe |find ".exe" >>"%temp%\\o-help-list.txt" 
      echo.                     >>"%temp%\\o-help-list.txt" 
      dir /d *.bat |find ".bat" >>"%temp%\\o-help-list.txt" 
      popd

      rem Strip extensions and report just names
      rem c.f. http://ss64.com/nt/syntax-replace.html
      for /f "usebackq delims=?" %%g in ("%temp%\\o-help-list.txt") do (
        set _s=%%g
        set _s=!_s:.exe=!
        set _s=!_s:.bat=!
        echo.       !_s!
        )
      echo.
      del "%temp%\\o-help-list.txt" 

      rem Report gdal version, if present
      for %%g in (gdalinfo.exe) do if not ["%%~dp$PATH:g"]==[] gdalinfo --version

  goto :EOF

:NoEnv
  echo    ERROR: OSGEO4W_ROOT is not set
  echo.

The previous error does not come up, but gdalinfo crashes in the end.

I have independently applied the same corrections to osgeo4w.bat and o-help.bat proposed by Andre Joost and can confirm that these modifications correct the errors for both the standalone install (1.8.0.1) and the OSGeo4W package based install (GDAL 1.9.1-2) on Win7.

I have raised a ticket duplicating most of this on the OSGeo4W trac (http://trac.osgeo.org/osgeo4w/ticket/315)
