awesome/client.c
Fabienne Ducroquet b12a5235a5 [doc] Fix some typos, modify a few descriptions 
Before awesome 2.3 release, I've decided to look for typos in the
awesome* manpages, here is the result. I've also modified some options'
descriptions that I didn't find very clear, I hope I have not
added/missed too many mistakes as I'm not a native English speaker...
