a fairly large number of elisp files, including munging the feature symbol.

 Looking at my 1000+ package sample, I see the following appear to have more
mundane occurrences of elisp file in subdirectories:


   - all-the-icons
   - auctex
   - axiom-environment
   - ecb
   - elisp-benchmarks
   - elpy (.yas-setup.el)
   - ert-runner
   - irony (tests)
   - julia-snail
   - parser-generator (tests)
   - requirejs (.yas-compiled-snippets.el)
   - slime
   - sly
   - taxy (examples)
   - yasnippet-snippets (.yas-setup.el)
