* Memory allocation NULL check: this is a bona-fide bug introduced by my refactoring * MAX_FILE_SIZE: I don't think this is true. * skip_until_charset, skip_charset bound check bug: I don't think this is true * Uninitialized value_end: I don't think this is true - and if true should be caught by -Wall -Werror flags. * argc < 1 check not being necessary: This is not true, you can make argc == 0 by using the exec family of libc functions. * Error Handling: Currently all parsing errors should cause the program to exit, which I think is the desired behavior. * Unsanitized input for .env: Intended behavior. * Unsanitized input for execvp: Intended behavior.
