1. Fix a misspelled variable to avoid shell namespace pollution
2. Remove a bogus completion (the 'brew xo' one)
3. Add missing tab completion code for
   - Several arguments/commands (options, --cellar etc.)
   - Aliases (e.g. home and homepage)
   - 'brew edit' complete to all formulae, not just installed ones

i.e. `--force --debug --use-llvm --ignore-dependencies --HEAD`

Additionally:

 * Use a cleaner `if` block in install options completion case.
 * De-dupe options for subsequent completion (e.g. stop offering --foo once
   --foo option has been used).

To trigger the option autocompletion, type:

    brew install foo --[tab][tab]

We were checking that at least one URL argument was added but
the --install parameter was also counted in that.

Move all documented "external commands" up with the resto f the commands,
as these will all be built-in commands after the next code re-org.

Also, revise main man page, and update brew-man command to handle
multiple input files.

* Don't link .DS_Store files
* Don't list .DS_Store files in `brew info`

Having $MACOSX_DEPLOYMENT_TARGET (for Fink) to something other than
the current system SDK will cause Git to fail to compile (when building
the Python bindings).
