[FEATURE] - Improve Paste command behavior beyond #64

[alefragnani]

PR #64 added a setting overwrite the word only when the cursor is in the middle of the word. The idea is to update that setting to allow 3 behaviors

• original builtin paste behavior: paste in the cursor location
• extension behavior: paste replacing the current word
• PR #64 behavior: only overwrite when the cursor is in the middle of the word
