* man/du.x: Change ".BR" to ".B" if there is only one argument.
Protect an end-of-sentence indicator (.?!) with '\&'
if it does not mean an end of a sentence.
Change '--' to '\-\-' if it indicates an option.
* man/rm.x: Change '\=' to '='.

 [PATTERNS]
 PATTERN is a shell pattern (not a regular expression).  The pattern
-.BR ?
+.B ?\&
 matches any one character, whereas
-.BR *
+.B *
 matches any string (composed of zero, one or multiple characters).  For
 example,
-.BR *.o
+.B *.o
 will match any files whose names end in
 .BR .o .
 Therefore, the command
 .IP
-.B du --exclude=\(aq*.o\(aq
+.B du \-\-exclude=\(aq*.o\(aq
 .PP
 will skip all files and subdirectories ending in
-.BR .o
+.B .o
 (including the file
-.BR .o
+.B .o
 itself).
