Stack temporary ghci-scripts created with group write permissions doesn't work ghci-ng

[phenguin]

Hey there,

I'm trying to get stack to play nicely with ghci-ng and I'm having issues with the permissions on the temporary ghci-script files stack is creating when running "stack ghci --with-ghc=ghci-ng". ghci-ng complains when trying to execute any ghci script that has group or other write permissions, and from running an strace on the stack ghci command above, I saw that stack was creating these temp scripts with 0666 permissions. This causes me to get a message like "WARNING: /tmp/username/ghci-script234234/ghci-script is writable by someone else. IGNORING!" when running the command. In addition, the project modules are not loaded either (because the script isn't run). Is there a workaround for this issue? Also, is there a reason why these temp file couldn't be created with more restricted permissions, say 0644?

Thanks

@phenguin Good point! I don't get these warnings, but I've added some code to set the permissions. Please reopen if the issue isn't fixed in the latest development version.
