[Bug gdb/10909] New: segfault when STARTUP_WITH_SHELL = 0, in breakup_args.

["scott dot sourceware dot 2009 at scottrix dot co dot uk" <sourceware-bugzilla at sourceware dot org>]

Setting STARTUP_WITH_SHELL to 0 in inferior.h means that gdb segfaults when
trying to run a program with arguments.  This is because of the code:

-      cp = strchr (cp, ' ');
-      if (cp == NULL)
-  cp = strchr (cp, '\t');
-      if (cp == NULL)
-  cp = strchr (cp, '\n');

Which is clearly broken.  While google I found a post which suggests this
problem has been there since at least 5.3 !!!.  I will attach a suggested patch.
