the right way to delete a mistake in file contexts

[mark]

What's the *correct* way to delete a mistake. I just did an semanage
fcontext, and in the wildcard, had *., rather than .*. I seem to have made
selinux stop complaining by deleting the line from
/etc/selinux/targeted/contexts/files/file_contexts.local and
/etc/selinux/targeted/modules/active/file_contexts.local, but I doubt
that's the recommended method....
