Clarify notes on dependency errors, tests, and VCS integration.

An optional feature that suggests you install Python is okay;
core-dumping is not.

The note on tests was about fish development tests, not the `test`
builtin for conditional syntax.

Specifically mention git, hg, and svn in the VCS section.

@ -31,6 +31,8 @@ To make linting the code easy there are two make targets: `lint` and `lint-all`.
Fish has custom cppcheck rules in the file `.cppcheck.rule`. These help catch mistakes such as using `wcwidth()` rather than `fish_wcwidth()`. Please add a new rule if you find similar mistakes being made.
Fish also depends on `diff` and `expect` for its tests.
### Dealing With Lint Warnings
You are strongly encouraged to address a lint warning by refactoring the code, changing variable names, or whatever action is implied by the warning.

Optional functionality should degrade gracefully. (If fish ever threw a syntax error or a core dump due to missing dependencies for an optional feature, it would be a bug in fish and should be reported on our GitHub.) Optional features and dependencies include:
* fish's builtin `test` syntax, which requires `diff` and `expect`. You don't need these, though, if you don't want to use our tests.
* dynamically generating usage tips for builtin functions, which requires man, apropos, nroff, and ul.
* manual page parsing for auto-completion for external commands, which also requires the above man tools, plus Python 2.6+ or Python 3.3+. Python 2 will also need the backports.lzma package; Python 3.3+ should include the required module by default.
* the web configuration tool, which requires Python 2.6+ or 3.3+.
* the fish_clipboard_* functions (bound to \cv and \cx), which require xsel or pbcopy/pbpaste.
fish can also show VCS information in the prompt, when the current working directory is in a VCS-tracked project. This is one of the weakest dependencies, though: if you don't use git, you don't need git information in the prompt, and if you do use git, you already have it.
fish can also show VCS information in the prompt, when the current working directory is in a VCS-tracked project, with support for Git, Mercurial, and Subversion. This is one of the weakest dependencies, though: if you don't use git, for example, you don't need git information in the prompt, and if you do use git, you already have it. Similarly, fish comes with a variety of auto-completion scripts to help with command-line usage of a variety of applications; these scripts call the application in question, but you should only need these applications if you use them.
