/* FIO_removeMultiFilesWarning() :
* Returns 1 if the console should abort, 0 if console should proceed.
* Based on displayLevelCutoff (typically == 1) and the global setting g_display_prefs.displayLevel, this
* function may print a warning message, a user prompt, both, or none.
* This function handles logic when processing multiple files with -o, displaying the appropriate warnings/prompts.
*
* If -f is specified, or there is just 1 file, zstd will always proceed as usual.
* If --rm is specified, there will be a prompt asking for user confirmation.
* If -f is specified with --rm, zstd will proceed as usual
* If -q is specified with --rm, zstd will abort pre-emptively
* If neither flag is specified, zstd will prompt the user for confirmation to proceed.
* If --rm is not specified, then zstd may print a warning to the user.
