Then lets add:
backtick Pfilehandle, Scommand, Imode
backtick Pfilehandle, Scommand, Imode, Pargarray
to the ops list. The first form just creates a new shell and passes in the
command as one big lump (quoting issues and all), while the second takes
an array of parameters and execs the command with those passed-in
parameters. Mode can be a bitmask:
bit 0: handle ties command's stdin
bit 1: Handle ties command's stdout
bit 2: handle ties command's stderr
bit 3: Fork the process
And yes, I know that Unices can't all tie multiple filehandles to child
processes well. That's fine, no reason to penalize the OSes that can...
