Duplicates

If you have duplicate detection, you may run into false positives, here are some examples of ways to suppress them:

# mounts
mount (?:-n |)-t (\w+)\s+\g{-1}

Notes

patterns operate on a per line basis
the first match wins, and matches are replaced by a single space character -- roughly resulting in the matched content being treated as a word break (and not seen by the word checker)
- the behavior may change such that the length of a replacement matches the length of the replaced content...
there is no support for multiline patterns, see Feature: Block Ignore for my current thoughts
