"invalid lua in p8" error for a comment in a .lua file
I have a .p8 base file with a stack of .lua files as imports.
The program is running just fine and is in the final testing stages.
But, it exceeds the compressed limit for Pico-8.

When I try to use shrinko8, I get the error
`ERROR: Invalid lua line in p8 file (line #249)`

I accidentally discovered that it is actually one of the .lua files, not the lone .p8 file.
That file contains this comment
`--z3/4 formula is "r = r + 2 ∗ L + 1"`

If I change that comment to remove the `*` it stops complaining.
`--z3/4 formula is "r = r + 2  L + 1"`

So this is a two-parter:
1. It incorrectly told me the .p8 file was the problem, when it was a .lua file
2. A * character in a comment shouldn't cause such issues, I think.
