[Bug 1366451] Re: "mksh -v" should display mksh's version number, plus the attached chunk of text, onscreen

[Jason Spiro]

By the way, do here-documents work okay on modern versions of Android?
Or is there no place for mksh to write the required temporary files to
make them work?

Title:
  "mksh -v" should display mksh's version number, plus the attached
  chunk of text, onscreen

Bug description:
  It's customary in the Unix world that "-v" or "--version" displays a
  program's version. If someone is logged into an Android device, you
  want to make it easy for them to find out which shell is installed.
  How can you do this? One way is to offer a "-v" option which will tell
  them the answer (and will also tell them mksh's version number).

  May I suggest that, if the user runs "mksh -v", then mksh should echo
  the following to stdout, after which it should immediately exit.

  --- cut here ---
  mksh R50b+cvs
