bug#46808: Man page of "tail"

[Reuti]

Hi,

I noticed some formatting issues in the man page of `tail`, and I wonder 
whether they are intentional as they occur at some places. They happen up to 
version 8.32:

line: "-c, --bytes=[+]NUM" the "[" is in italic: \fB\-c\fR, 
\fB\-\-bytes\fR=\fI\,[\/\fR+]NUM
line: "-f, --follow[={name|descriptor}]" the "[=" is in bold: \fB\-f\fR, 
\fB\-\-follow[=\fR{name|descriptor}]
line: "-n, --lines=[+]NUM" the "[" is "[" is in italic: \fB\-n\fR, 
\fB\-\-lines\fR=\fI\,[\/\fR+]NUM

I'm not a `groff` expert, but the sequence "\,some-text\/" appears a couple of 
times. What effect does it have for the formatting as the "," and "/" are not 
output?
