misc-utils/getopt.1: minor corrections to the manual

Input file is getopt.1

Test nr. 2:

Enable and fix warnings from 'test-groff'.

Input file is /tmp/getopt.1

<getopt.1>:5 (macro BI): only 1 argument, but more are expected
<getopt.1>:419 (macro IR): only 1 argument, but more are expected
<getopt.1>:421 (macro IR): only 1 argument, but more are expected

chk_manuals: Output is from: test-groff -b -e -mandoc -T utf8 -rF0 -t -w w -z

  and

Test nr. 15:

Change the name of a macro for two fonts (e.g., BR and IR) to one letter,
if there is only one argument.
Add the second argument if needed.  It is sometimes part of the first one.

Protect a full stop (.) with "\&", if it has a blank (white-space) in front
of or (ignoring transparent characters to the full stop) after it, and it does

Test nr. 20:

Use a macro to change to the italic font, instead of \fI [1], if
possible.
The macros have the italic corrections, but "\c" removes them.

Test nr. 28:

Wrong distance between sentences or protect the indicator.

1) Separate the sentences and subordinate clauses; each begins on a new
line.  See man-pages(7) and "info groff".

2) Adjust space between sentences (two spaces),
