Reproduce:
Add to some executable stanza the lines: -with-rtsopts="-N -A32m"
Personally, I obtained this UnitInfo via logs from HIE and couldnt figure out how to use plain cabal-helper for this.

Expected:
I would expect it to be parsed as one flag.

-with-rtsopts="-N -A32m" is the wrong syntax. Cabal expects Haskell style strings, not shell style, so: "-with-rtsopts=-N -A32m". See https://www.haskell.org/cabal/users-guide/developing-packages.html#package-descriptions

Cabal should probably complain about the stray " though, I'd report a Cabal bug.
