`re` docs never say that the ASCII flag affects `\p{...}` properties

Documentation

https://docs.python.org/dev/library/re.html#re.A

The re.ASCII entry lists \w, \W, \b, \B, \d, \D, \s and \S as the constructs it restricts, and the \p{property=value} section never mentions the flags. Six accepted property spellings are restricted by the flag as well, because Nd, digit, word, space, White_Space and WSpace are matched with the same engine categories as \d, \s and \w. The other 52 accepted spellings are unaffected.

$ cat repro.py
import re
s = '0\u0663 \xa0x'
for p in 'Nd', 'digit', 'word', 'space', 'White_Space', 'WSpace':
    pat = r'\p{%s}' % p
    print('%-12s %-18r %r' % (p, re.findall(pat, s), re.findall(pat, s, re.ASCII)))

$ ./python repro.py
Nd           ['0', '٣']         ['0']
digit        ['0', '٣']         ['0']
word         ['0', '٣', 'x']    ['0', 'x']
space        [' ', '\xa0']      [' ']
White_Space  [' ', '\xa0']      [' ']
WSpace       [' ', '\xa0']      [' ']

Expected: the \p{property=value} section says which properties the ASCII flag restricts, alongside the existing note that space follows str.isspace and xdigit matches only the ASCII hexadecimal digits.

\p{White_Space} and \p{WSpace} are also absent from the documented list of supported properties, although both are accepted.

Inizia con la documentazione di re.ASCII all’indirizzo docs.python.org/dev/library/re.html#re.A, quindi leggi la sezione \p{property=value} e il relativo elenco delle proprietà supportate. Documenta quali sei forme di proprietà sono limitate da ASCII e aggiungi White_Space e WSpace all’elenco delle proprietà supportate, mantenendo le note esistenti su space e xdigit.
