Add individual documentation pages for string's subcommands This adds string-x.rst for each subcommand x of string. The main page (string.rst) is not changed, except that examples are shown directly after each subcommand. The subcommand sections in string.rst are created by textual inclusion of parts of the string-x.rst files. Subcommand man pages can be viewed with either of: ``` man string collect man string-collect string collect <press F1 or Alt-h> string collect -h ``` While `string -h ...` still prints the full help. Closes #5968

Description
-----------
.. BEGIN DESCRIPTION
Add `string sub --end` (#6765)
2020-03-22 22:53:09 +08:00
``string sub`` prints a substring of each string argument. The start/end of the substring can be specified with ``-s``/``-e`` or ``--start``/``--end`` followed by a 1-based index value. Positive index values are relative to the start of the string and negative index values are relative to the end of the string. The default start value is 1. The length of the substring can be specified with ``-l`` or ``--length``. If the length or end is not specified, the substring continues to the end of each STRING. Exit status: 0 if at least one substring operation was performed, 1 otherwise. ``--length`` is mutually exclusive with ``--end``.
