* \brief Pre-process command line arguments to preserve compatibility with
* getopt behavior.
*
* getopt and glib have slightly different behavior when it comes to processing
* single command line arguments. getopt allows this: -x, while glib will
* try to handle like it is additional single letter arguments. glib
* prefers -x instead.
*
* This function scans argv, looking for any single letter command line options
* (indicated by the 'special' parameter). When one is found, everything after
* that argument to the next whitespace is converted into its own value. Single
* letter command line options can come in a group after a single dash, but
* this function will expand each group into many arguments.
*
* Long options and anything after "--" is preserved. The result of this function
* can then be passed to ::g_option_context_parse_strv for actual processing.
*
* In pseudocode, this:
*
* pcmk__cmdline_preproc(4, ["-XbA", "--blah=foo", "-aF", "-Fval", "--", "--extra", "-args"], "aF")
*
* Would be turned into this:
*
* ["-X", "-b", "-A", "--blah=foo", "-a", "F", "-F", "val", "--", "--extra", "-args"]
*
* This function does not modify argv, and the return value is built of copies
* of all the command line arguments. It is up to the caller to free this memory
* after use.
*
* \param[in] argc The length of argv.
* \param[in] argv The command line arguments.
* \param[in] special Single-letter command line arguments that take a value.
* These letters will all have pre-processing applied.
