Alexander Schmolck 8d4b6766e2 Convert short nix options to long ones 
e.g. nix-env -e subversion => nix-env --uninstall subversion

The aim is to make the documentation less cryptic for newcomers and the
long options are more self-documenting.

The change was made with the following script:

<https://github.com/aschmolck/convert-short-nix-opts-to-long-ones>

and sanity checked visually.

Name

nix-env --switch-generation - set user environment to given profile generation

Synopsis

nix-env {--switch-generation | -G} generation

Description

This operation makes generation number generation the current generation of the active profile. That is, if the profile is the path to the active profile, then the symlink profile is made to point to profile-generation-link, which is in turn a symlink to the actual user environment in the Nix store.

Switching will fail if the specified generation does not exist.
