Alternate H.ghci does not work under Ubuntu Linux

[djsamperi]

Describe the bug Under Ubuntu Linux, H can be started with stack --nix exec H But if I modify H/H.ghci and use stack --nix exec ghci -- -ghci-script H/H.ghci there is no error message, but H mode is not enabled. Does not recognize [r|3|], for example.

To Reproduce Modify H/H.ghci and start H as described above.

Expected behavior Should start ghci with H capabilities. Should recognize [r|3|] and not complain there is a syntax error.

Environment Ubuntu Linux Version 22.04

Additional context No problem under Windows using stack exec ghci -- -ghci-script H/H.ghci
