Eelco Dolstra 973c9abdbe Fix info command
The "info" command has been broken on NixOS since
457fdb38425fd00378f213f9bd5c306ed99395bf (proving that nobody uses
info).

# Quick hack to make the `info' command work properly. `info' needs
# a "dir" file containing all the installed Info files, which we
# don't have (it would be impure to have a package installation
# update some global "dir" file). So this wrapper script around
# "info" builds a temporary "dir" file on the fly. This is a bit
# slow (on a cold cache) but not unacceptably so.
