Readme command-line options inconsistent

[jx2zhou]

The readme for this project shows the usage guidelines ...

Usage

brainfuck [-ch] <filenames>
-e  run code directly
-h  show a help message.

... but is unclear as to whether -c or -e is actually the option for running code directly. This could be figured out really quickly by running the program, but I think it'd be beneficial from making the command-line options more unambiguous.

Ah, my apologies.

Initially, the -c or --code option was used to run brainfuck code via the command line, but we eventually updated it to -e and --eval and I forgot to update that part in the readme.

Thank you for noticing!
