Johannes Altmanninger 97db9d5c38 docs synopses: fix alignment of continuation lines
This corrects what looks like wrong alignment of some synopsis lines.
(I think the alignment is not a bad idea but it makes us do more
manual work, maybe we can automate that in future.  We still need to
figure out how to translate it to HTML.)

"man -l build/user_doc/man/man1/history.1" before:

	string match [-a | --all] [-e | --entire] [-i | --ignore-case]
	            [-r | --regex] [-n | --index] [-q | --quiet] [-v | --invert]
	            PATTERN [STRING…]

and after:

	string match [-a | --all] [-e | --entire] [-i | --ignore-case]
	             [-r | --regex] [-n | --index] [-q | --quiet] [-v | --invert]
	             PATTERN [STRING…]

Also make the lines align the same way in the RST source by carefully
choosing the position of the backslash. I'm not sure why we used
two backslashes per line. Use only one; this gives us no choice
of where to put it so both source and man page output are aligned.
Change tabs to spaces to make the alignment in the source work.

string-sub - extract substrings
===============================
Synopsis
--------
.. BEGIN SYNOPSIS
``string`` sub [(**-s** | **--start**) *START*] [(**-l** | **--length**) *LENGTH*]
\ [**-q** | **--quiet**] [*STRING* ...]
.. END SYNOPSIS
Description
-----------
.. BEGIN DESCRIPTION
``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``.
.. END DESCRIPTION
