Replace ambiguous word "pound" by "hash" in difflib docs

[George-Ogden]

This clears up what is meant by IS_LINE_JUNK and explains refers to # as "the pound or hash symbol", rather than just "the pound symbol", which could mean £.

I think we make it pretty clear with "('#')". As for your suggestion, adding "of the pound, or hash symbol" just makes it less clear IMO, as now it seems like we explicitly allow '£' OR '#'.

@StanFromIreland, is there a way to do the indentation automatically in Vim/bash/VSCode? I've been doing it manually, which is why it looks odd.

[StanFromIreland]

Possibly your editor has a default that is different than that of the file? Even in the docs the indentation can vary from file to file, I have made such a mistake before.

Note that I totally agree with this change because I never knew that it was called a "pound" character. For me it was either the cardinality of something, or a hash(tag).

[StanFromIreland]

I've also never heard it used in Europe, I am familiar with the term via American media.
