No need. Just keep it as:

	JFS Homepage:  http://jfs.sourceforge.net/

Sphinx will do the right thing when it finds a URL that starts with
http/https.

Please preserve as much as possible the original format.

If you just place the mount option on one line and the description at the
next one, e. g.:

	iocharset=name
	              	Character set to use for converting from Unicode to
	                ASCII.  The default is to do no conversion.  Use
	                iocharset=utf8 for UTF-8 translations.  This requires
	                CONFIG_NLS_UTF8 to be set in the kernel .config file.
	                iocharset=none specifies the default behavior explicitly.

	resize=value
	            	Resize the volume to <value> blocks.  JFS only supports
	                growing a volume, not shrinking it.  This option is only
	                valid during a remount, when the volume is mounted
	                read-write.  The resize keyword with no value will grow
	                the volume to the full size of the partition.
...

It will produce a very nice output, and the changes will be minimum,
without any special markup.

> -The following mount options are supported:
> -(*) == default
> -
> -iocharset=name	Character set to use for converting from Unicode to
> -		ASCII.  The default is to do no conversion.  Use
> -		iocharset=utf8 for UTF-8 translations.  This requires
> -		CONFIG_NLS_UTF8 to be set in the kernel .config file.
> -		iocharset=none specifies the default behavior explicitly.
> -
> -resize=value	Resize the volume to <value> blocks.  JFS only supports
> -		growing a volume, not shrinking it.  This option is only
> -		valid during a remount, when the volume is mounted
> -		read-write.  The resize keyword with no value will grow
> -		the volume to the full size of the partition.
> -
> -nointegrity	Do not write to the journal.  The primary use of this option
> -		is to allow for higher performance when restoring a volume
> -		from backup media.  The integrity of the volume is not
> -		guaranteed if the system abnormally abends.
> -
> -integrity(*)	Commit metadata changes to the journal.  Use this option to
> -		remount a volume where the nointegrity option was
> -		previously specified in order to restore normal behavior.
> -
> -errors=continue		Keep going on a filesystem error.
> -errors=remount-ro(*)	Remount the filesystem read-only on an error.
> -errors=panic		Panic and halt the machine if an error occurs.
> -
> -uid=value	Override on-disk uid with specified value
> -gid=value	Override on-disk gid with specified value
> -umask=value	Override on-disk umask with specified octal value.  For
> -		directories, the execute bit will be set if the corresponding
> -		read bit is set.
> -
> -discard=minlen	This enables/disables the use of discard/TRIM commands.
> -discard		The discard/TRIM commands are sent to the underlying
> -nodiscard(*)	block device when blocks are freed. This is useful for SSD
> -		devices and sparse/thinly-provisioned LUNs.  The FITRIM ioctl
> -		command is also available together with the nodiscard option.
> -		The value of minlen specifies the minimum blockcount, when
> -		a TRIM command to the block device is considered useful.
> -		When no value is given to the discard option, it defaults to
> -		64 blocks, which means 256KiB in JFS.
> -		The minlen value of discard overrides the minlen value given
> -		on an FITRIM ioctl().
