POSIX requires $PWD to be reliable, and we expect all

POSIX. Thus, it is smarter to avoid forking the pwd
executable for something that is already available in
the environment.
So replac it with the following:
sed -i 's/`pwd`/$PWD/g' $(git grep -l "\`pwd\`")
sed -i 's/$(pwd)/$PWD/g' $(git grep -l "\$(pwd)")
The remaining small parts are manually modified.

This is now pointless. I'm deleting the line instead.
