Set working directory when calling pico8 -run

[merwok]

Hello and thanks for this package!

My projects are in sub-sub-directories of the pico-8 carts location, or in other directories entirely. I usually run !pico8 -run % which works as pico-8 interprets the relative path correctly (I have autochangedir note), it does not try to load the filename from its carts directory. With :Pico8Run I get loading errors. I think the current working directory should be set for the pico-8 process, or the absolute file path should be passed.

Thank you for your report! I could not reproduce the problem on my Windows environment, but it seems better to pass the absolute file path. Please update the plugin and check if your problem has been resolved.

Thanks for the quick reply!

I updated and still have a loading error with the absolute path. I will try to find more info!

I ran with strace and found that this path is tried:

openat(AT_FDCWD, "/home/user/working/dir/'/home/user/working/dir/cart.p8'", O_RDONLY) = -1 ENOENT

So pico8 is already aware of the working directory, but passing a full path leads to bad concatenation. I am reverting the change you did to see the original issue.

[merwok]

The original issue was a bad path too: "/home/user'/home/user/working/dir/cart.p8'" Feels that pico-8 wants an unexpanded, unquoted relative path!

This change works for me with the autochdir option active, but not without!
