It's silly with the example of '-dir' it's much less silly with
a string like ' \t'.
The doc is rather clear about it:
str.rstrip([chars])
It is marked 'chars' and not 'suffix'
The textual description is even clearer:
"The chars argument is not a suffix; rather, all combinations of its
values are stripped:"
When I asked in this grpup about a way of how to strip off a prefix I
never even considered strip as a solution having read the doc before.
I also think, that the functionality of strip / rstrip is useful as is.
It would just be great to have functions to strip prefixes/suffixes.
If these new commands were alphabetically next to the classic commands,
( e.g. strip_prefix / rstrip_suffix) then almost everybody looking for
string functions would probably use the function, which is appropriate
for his purpose.
Breaking backwardscompatibility within python 3 might not be the best
choice.
