Document how to escape a date/time format character for the |date and |time filters.

[Baptiste Mispelon]

The current documentation for the ​date and ​time filters doesn't explain how to escape a format character.

It's only documented as part of the ​now template tag:

Note that you can backslash-escape a format string if you want to use the “raw” value. In this example, both “o” and “f” are backslash-escaped, because otherwise each is a format string that displays the year and the time, respectively:
It is the {% now "jS \o\f F" %}
This would display as “It is the 4th of September”.

Historically, the big table with all the available format characters used to be next to the documentation for {% now %} but it was moved at some point (to be with the documentation for |date.

I would suggest moving the paragraph about backslash escape under the table of all formats instead (or least duplicating it there too).

date documentation contains an example with escaped format characters:

outputs 9 de Enero de 2008 (the DATE_FORMAT format specifier for the es locale is r'j \d\e F \d\e Y'.

so maybe we can add a short explanation to this example, e.g.:

outputs 9 de Enero de 2008 (the DATE_FORMAT format specifier for the es locale is r'j \d\e F \d\e Y'). Both “d” and “e” are backslash-escaped, because otherwise each is a format string that displays the day and the timezone name, respectively.

I also agree to duplicate backslash example to the time documentation.
