Disable path checking by directory

[danielshahaf]

RFE: Disable path checking for some directories but not others. Similar to the vcs_info disable-patterns style. This would be useful under expensive-to-readdir()/stat() mountpoints (e.g., sshfs).

This would need to check several things:

• Absolute filenames under DIR: % stat /victim/foo/bar
• Relative paths that resolve to paths under DIR (could use the :a modifier here, since it's disk-agnostic): % stat ../victim/foo/bar
• Any paths, when cwd is DIR: /victim% stat foo (where the prompt displays cwd)
• Any of the foregoing, as a command word: % /victim/foo/bar

Tentatively adding to 0.7.0 milestone.

Any suggested array name? I think something like this would do the trick.

XXX = DIRS_BLACKLIST

:P requires a new zsh, also it can access disk (as can the [[ tests right above) so we need to be careful, is just readdir() expensive or also stat()?

Making path local requires -h (-H?).

Excuse brevity.
