fix to spaces in path

This is your gadfly speaking. I'd like to commit the patch that fixes the spaces in path issue. Perhaps a show of hands in favor of fixing this problem would help move things along? Here is a list of the problems with spaces in paths that are solved by this fix: - pear install to a subdirectory of "C:\Program Files" will not work. "C:\Program Files" is the most commonly used install directory on windows - pear package will not work in any subdirectory containing spaces, and will create and possibly overwrite folders of the same name as the suffix. So if you have 2 directories "C:\Web" and C:\Web Pages", the pear package command will overwrite the contents of C:\Web and fail with a cryptic error message about not being able to copy a random file with .tmp pre-pended to it - the new publicweb role which is proposed will not allow installation to "C:\Program Files\Apache Group", the default Apache location on windows. backwards compatibility issues: none - this patch is internal, and uses pre-programmed features of the same functions to do the job. API issues: none - no changes are visible to private or public functions, no other code need be changed. All in favor of fixing these bugs please +1, this will at least start the ball rolling. For those wishing to test or review this fix, I've attached the patch Greg
