ignore: support backslash escaping

Browse Source 
Use the new `Globset::backslash_escape` knob to conform to git behavior:
`\` will escape the following character. For example, the pattern `\*`
will match a file literally named `*`.

Also tweak a test in ripgrep that was relying on this incorrect
behavior.

Closes #526, Closes #811
