README suggestions

[paddymul]

I was trying to do a PR on a different project, and I had aPR that introduced a reasonable misspelling for a single test file. After reading the README I couldn't figure out how to add an ignore/override for a single file.

I understand that

[type.po]
extend-glob = ["*.po"]
check-file = false

ignores a file

I understand that

[default.extend-identifiers]
# *sigh* this just isn't worth the cost of fixing
AttributeIDSupressMenu = "AttributeIDSupressMenu"

but it's not clear how to add a rule for a single file

I think an example like this would be a very helpful addition to the README

Just after the two fragments you mentioned, the README says

If you need some more flexibility, you can completely exclude some files from consideration:

[files]
extend-exclude = ["localized/*.po"]

[epage]

Hmm, if you were wanting to instead extend-identifiers for a single file, we don't support that at the moment (unless you are willing to make its own file type, you can use file names but not file paths).

We do support default.extend-ignore-re which can be used to make emulate inline excludes (#316)

As the documentation covers what we have and we have issues for others, I'm going to go ahead and close this. If there is a reason we should reconsider, let us know!

Closing it is fine. Like I said, I encountered this problem when making a first contribution to another project. I'm not an active user of the project. I thought I'd provide the feedback and see if it's helpful.
