Every program using the cygwin32 DLL includes startup code to check
whether it is running under a shell also using cygwin32.  If so, the code
assumes the shell already did argument globbing at it leaves the arg
list alone.  If not, the startup code does the argument processing and
globbing itself (it assumes the program is running under COMMAND.COM
or CMD.EXE).  This allows programs to take "wildcard" arguments
regardless of the shell they're running under.
