PLE2502 documentation does not match the implementation

[dscorbett]

The documentation for bidirectional-unicode (PLE2502) says it checks for “bidirectional unicode characters”. That phrasing is imprecise (a string can be bidirectional but any given character isn’t) but the example code implies it means “right-to-left characters”. However, PLE2502 only checks for a selection of bidi control characters. Not all bidi control characters are right-to-left, and most right-to-left characters are ignored by the rule.

The documentation includes this example:

s = "א" * 100  #  "א" is assigned
print(s)  # prints a 100-character string

However, there is no violation of PLE2502 in that example.
