sys-utils/fallocate.1: Some tidying of the manual

Test nr. 2:

Enable and fix warnings from 'test-groff'.

Input file is /tmp/fallocate.1

<fallocate.1>:10 (macro IR): only 1 argument, but more are expected
<fallocate.1>:24 (macro RB): only 1 argument, but more are expected
<fallocate.1>:25 (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.

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. 27:

Split lines longer than 80 characters into two or more lines.
Apropriate break points are the end of a sentence and a subordinate
clause.

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".

Or

2) Adjust space between sentences (two spaces),

3) or protect the indicator by adding "\&" after it.

The "indicator" is an "end-of-sentence character" (.!?).

Have a space after a comma in an argument to an alternating fonts macro.
The space belongs to the comma, so ', '.

+For filesystems which support the fallocate system call,
 preallocation is done quickly by allocating blocks and marking them as
