   matches with one of the options in struct 'my_option'.
   Check that option was given an argument if it requires one
   Call the optional 'get_one_option()' function once for each option.
+
+  Note that handle_options() can be invoked multiple times to
+  parse a command line in several steps.
+  In this case, use the global flag @c my_getopt_skip_unknown to indicate
+  that options unknown in the current step should be preserved in the
+  command line for later parsing in subsequent steps.
+
+  For 'long' options (--a_long_option), @c my_getopt_skip_unknown is
+  fully supported. Command line parameters such as:
+  - "--a_long_option"
+  - "--a_long_option=value"
+  - "--a_long_option value"
+  will be preserved as is when the option is not known.
+
+  For 'short' options (-S), support for @c my_getopt_skip_unknown
+  comes with some limitation, because several short options
+  can also be specified together in the same command line argument,
+  as in "-XYZ".
+
+  The first use case supported is: all short options are declared.
+  handle_options() will be able to interpret "-XYZ" as one of:
+  - an unknown X option
+  - "-X -Y -Z", three short options with no arguments
+  - "-X -YZ", where Y is a short option with argument Z
+  - "-XYZ", where X is a short option with argument YZ
+  based on the full short options specifications.
+
+  The second use case supported is: no short option is declared.
+  handle_options() will reject "-XYZ" as unknown, to be parsed later.
+
+  The use case that is explicitly not supported is to provide
+  only a partial list of short options to handle_options().
+  This function can not be expected to extract some option Y
+  in the middle of the string "-XYZ" in these conditions,
+  without knowing if X will be declared an option later.
+
+  Note that this limitation only impacts parsing of several
+  short options from the same command line argument,
+  as in "mysqld -anW5".
+  When each short option is properly separated out in the command line
+  argument, for example in "mysqld -a -n -w5", the code would actually
+  work even with partial options specs given at each stage.
