Don't use the debug flag by default.

Hi all,

lsp-haskell/lsp-haskell.el

Line 438 in c443f15

`("-d" "-l" ,lsp-haskell-server-log-file)

enables the debug flag by default, which causes the language server to dump log to disk and become unresponsive. I think for most of the use cases, the debug flag is unnecessary. I can help remove the flag from default if this sounds reasonable.

Yeah, I agree that that seems like a mistake. I think it's probably helpful to have a logfile by default, but maybe even that is too opinionated?

[trivialfis]

Thank you for the reply. The log file is fine.

I opened an oneliner fix here: #180 .
