Detect imperatives with prefixes

Feature Request

Summary

git-sumi should detect imperatives with prefixes. For example, "write" is in the list of non-imperative verbs (as "written", "wrote"), but "rewrite" is not.

Motivation

It would improve non-imperative-verb detection.

Detailed Description

The logic to detect imperative verbs should not only match the first word against the hashset, but check whether it matches a list of prefixes + a word in the list.

As an initial list of prefixes, we could consider:

• re (reuse, reindex)
• un (undelete, unskip)
• pre (prebuilt, preinitialize)

Additional Context

It's probably a good idea to check for:

• [X] Base verb (this is implemented)
• [ ] Prefix + dash + verb
• [ ] Prefix + verb
