fast-import: document C-style escapes for paths

Simply saying “C-style” string quoting is imprecise, as only a subset of C escapes are supported. Document the exact escapes. Signed-off-by: Thalia Archibald <thalia@archibald.dev> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Certain characters must be escaped by preceding them with a backslash: `LF` is written as `\n`, backslash -as `\\`, and double quote as `\"`. All filenames can be represented as +as `\\`, and double quote as `\"`. Some characters may optionally be +written with escape sequences: `\a` for bell, `\b` for backspace, `\f` +for form feed, `\n` for line feed, `\r` for carriage return, `\t` for +horizontal tab, and `\v` for vertical tab. Any byte can be written with +3-digit octal codes (e.g., `\033`). All filenames can be represented as quoted strings. A `<path>` must use UNIX-style directory separators (forward slash `/`)
