[docs] [issue25433] whitespace in strip()/lstrip()/rstrip()

[Oliver Urs Lenz]

Oliver Urs Lenz <oliver.urs.lenz at gmail.com> added the comment:

Slightly tangential, but it would be great if the documentation of lstrip() and rstrip() could include an equivalent definition in terms of re.sub(), e.g.:

lstrip(foo) == re.sub(r'(?u)\A\s*', '', foo)
rstrip(foo) == re.sub(r'(?u)\s*\Z', '', foo)

(Or whatever else is correct.)
