  I don't understand the rsync example with '-e sh shell.c' as short-form options with space-separated values are expected to be two separate args and yet the glob expands it to a single arg. Right? Unless the tool does additional argument processing?

    '-e sh shell.c' as a single argument is the same as '-e' and ' sh shell.c' as separate arguments (see <https://pubs.opengroup.org/onlinepubs/9799919799/functions/getopt.html https://pubs.opengroup.org/onlinepubs/9799919799/functions/g...>). rsync executes ' sh shell.c' as a shell script and shells usually trim leading and trailing spaces when executing commands.
