[issue19175] Erroneous reference to "integer" in format string grammar

[Georg Brandl]

Georg Brandl added the comment:

The bug is that "integer" links to the "integer" production in the Python 
grammar.  This shouldn't happen; I'll have a look on the Sphinx side.

As a workaround, "integer" can be replaced by "digit+" as requested (it occurs 
twice).

[issue19175] Erroneous reference to "integer" in format string grammar

[David Chambers]

New submission from David Chambers:

I first raised this issue on Stack Overflow: 
http://stackoverflow.com/questions/19203194

The [replacement field grammar][1] states that an [integer][2] is a valid 
field_name, but this is inaccurate:

>>> '{0}'.format('zero')
'zero'
>>> '{0x0}.format('zero')
KeyError: '0x0'
>>> '{0o0}.format('zero')
KeyError: '0o0'
>>> '{0b0}.format('zero')
KeyError: '0b0'

This [comment][3] by Eric Smith suggests that the above is the intended 
behaviour:

> get_integer uses the narrowest possible definition for integer indexes,
> in order to pass all other strings to mappings.

The documentation should be updated to match the actual behaviour. abarnert on 
Stack Overflow suggested the following change:

-arg_name  ::=  [identifier | integer]
+arg_name  ::=  [identifier | digit+]
