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.

@ -643,7 +643,11 @@ When a `<path>` starts with a double quote (`"`), it is a C-style quoted
string, where the complete filename is enclosed in a pair of double
quotes and escape sequences are used. 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 `/`)
