Fix redundant import actions for names starting with _ #2483

@Ailrun Ailrun commented Dec 13, 2021

Names starting with _ is often used, for example, with lens among many others. However, the current redundant import action does not remove those even when they are redundant.

For instance,

import Control.Lens ((^.), _1, _2)

myVal = (1, 2) ^. _1

Here, _2 is redundant, but GHCIDE does not give any actions. Adding one more redundant import like

import Control.Lens ((^.), _1, _2, use)

gives the action, but the action removes only use, not _2.

This PR resolves this issue.

Instead of using a low-level `is_ident` that only works on ascii
characters. Instead match directly on the '_' character. The original
functionality has been restored (using `isAlpha` instead).

This commit removes the now unneccessary `is_ident` compat layer
