Please send patches using git-send-email.  Sending them as attachments 
makes it impossible to reply to them inline... which makes it really 
difficult to give review comments... as you can see below...

In the first patch, the commit message should be split into two lines. 
The first sentence makes a fine short message, and the second sentence 
make a fine follow-up.  Look at other commits to see how things are done.

Referring people to some random e-mail attachment seems awful.  Perhaps 
piglit should just include a minimal glinfo program that can be used 
when there's no wglinfo/glxinfo/eglinfo/etc. available on the system? 
It's already weird that we have some EGL tests, but no eglinfo logging, 
for example.

The last hunk in the second patch is garbage.  Every change in it 
changes correctly spelled words to misspelled words.
