Install Errors on Windows (Space in Pathname)

[boxfoot]

When I install a package on Windows that depends on optipng, npm spits out the following errors. I'm not sure if they're actually from optipng or from npm, but I thought I'd start here.

The problem seems to be connected to how command parameters are quoted (or not), and dealing with spaces in the pathname. To reproduce, set up a user on windows who has a space in their user name, and then try to install optipng with npm.
