Preserve order of extra-source-files from existing .cabal file #632
Description
Problem:
hpack reorders files in the extra-source-files section, which affects diff readability. Related: #617
Expected behavior:
Keep the original order exactly as written.
Example:
-- Before (Gild)
extra-source-files:
README.md
examples/jbeam/fender.jbeam
examples/jbeam/frame.jbeam
examples/jbeam/suspension.jbeam-- After (hpack)
extra-source-files:
README.md
JBFL_DOCS.md
examples/README.md
examples/jbeam/fender.jbeam
examples/jbeam/frame.jbeam
examples/jbeam/suspension.jbeam
