Optimise Derivation::unparse() 
In

  nix-instantiate --dry-run '<nixpkgs/nixos/release-combined.nix>' -A nixos.tests.simple.x86_64-linux

this reduces time spent in unparse() from 9.15% to 4.31%. The main
culprit was appending characters one at a time to the destination
string. Even though the string has enough capacity, push_back() still
needs to check this on every call.

Eelco Dolstra 2672a28bb4 nix dev-shell: Add --command option 
Note: like 'nix run', and unlike 'nix-shell', this takes an argv
vector rather than a shell command. So

  nix dev-shell -c 'echo $PATH'

doesn't work. Instead you need to do

  nix dev-shell -c bash -c 'echo $PATH'

Albert Safin f2a03acf3f nix-shell: clean up the tmpDir and escape variables 
The problem fixed: each nix-shell invocation creates a new temporary
directory (`/tmp/nix-shell-*`) and never cleans up.

And while I'm here, shellescape all variables inlined into the rcfile.
See what might happen without escaping:

    $ export TZ="';echo pwned'"
    $ nix-shell -p hello --run hello
    pwned
    Hello, world!

builtins.fetchGit: Fix build when fetching a git worktree

builtins.fetchGit: Fix build when fetching a git worktree 
Worktrees[1] are a feature of git which allow you to check out a ref in
a different directory.

While playing around with flakes I realized that git repositories in a
worktree checkout break when trying to build a flake:

```
$ git worktree add ../nixpkgs-flakes nixpkgs-flakes
$ cd ../nixpkgs-flakes
$ nix build .#hello
error: opening directory '/home/ma27/Projects/nixpkgs-flakes/.git/refs/heads': Not a directory
```

This issue has been fixed by determining with `git rev-parse --git-common-dir`
where the actual `.git` directory is.

Please note that this issue only exists on the `flakes` branch, fetching
worktree checkouts with Nix master seems to work fine.

Benjamin Hipple 762febafe2 doc: mention how to turn on pure evaluation mode in manual 
The flag is `--pure-eval`, which can be found by looking at the test suite; it
should be in the notes describing the feature as well, since otherwise users may
assume this is referencing something like `nix-shell --pure`.
