This patch implements an on-demand console window and enables OS/2 users to use
the -help and -version commandline parameters.  It adds a new function,
StartOS2App() which examines the commandline, and if needed, restarts the app in
a VIO session.  The function is intended to be called from xre_main() as early
in the startup processing as possible - in particular, before any other
commandline handling.

The patch also makes minor changes to xre_main and sNativeAppSupportOS2::Start.
It incorporates some of the OS/2 startup code in xre_main as well as a few lines
from Start.  It also modifies Start to remove -console and -dde from the
commandline arguments.  Without this change, a URL immediately following these
args would be ignored.

For lack of a better idea, I've added StartOS2App() to the end of
nsNativeAppSupportOS2 and placed its prototype in xre_main immediately preceding
the call to this function.

FYI... I will submit an xpfe version of this patch in the near future.

patch to implement console window
My c is really rusty but as I read the code I couldn't use both -dde and
-console, is this correct or am I misreading the code?  
Sorry, I read through the code once again and I think I was just misreading it.

> although your parenthesis style drives me crazy!

Which of the 6 different coding styles in ...AppSupportOS2 is yours?  Are you
the "don't let 'em touch" guy, e.g. if ([space]something[space])?  Please advise
and I will reformat accordingly (n.b. this offer does not extend to putting
braces around single lines - $#@%&!!).

No big deal. I'm just messing with you. 

I general prefer:

PRBool StartOS2App(int aArgc, char **aArgv);
  if (StartOS2App(gArgc, gArgv))
    return 1;


PRBool StartOS2App( int aArgc, char **aArgv);
  if (StartOS2App( gArgc, gArgv))
    return 1;

And yes, I know the argument about easily skipping around in an editor. The
truth be known, I don't even know what the keystroke in EPM is to go word by
word - I just go a character at a time :)

One more question on this.

I'm not sure on the naming. StartOS2App returns true if we are not going to
start the app, but restart.

Should be maybe call it something different?

updated patch per Comment #8

Per Comment #8 - I've left the name as-is but reversed the sense of the return:
 TRUE if the app should start, FALSE if it should terminate.

Also, per earlier comments, I've reformatted parenthesized expressions so as to
render Ctrl-Right substantially useless...

fixes bug in HandleCommandLine()

New code removes "-console" & "-dde" from commandline passed to a running
instance.  Without this, any URL following these args would be ignored.

when I use firefox!l.exe -help but it still displays the help.
Hadn't built with the xpfe changes yet.  -console and -version work fine, no
popuplog.os2 entries.
