Implement proper synopsis wrapping for HTML generation.

This was done in three pieces.  First, add HTML-specific tags to the POD to
mark the synopsis for HTML purposes so that we can apply style information
to it.  Second, update the style sheet to indent all lines except for the
first in the synopsis section.  Third, add the appropriate S<> tags around
option and argument pairs so that we don't wrap between the option and its
argument.

Unfortunately, due to the <I<foo>> style that looks nicer for other reasons,
we have to use the very verbose S<<< >>>.  Oh well.

=head1 NAME
fs diskfree - Shows data about the partition housing a directory or file
=head1 SYNOPSIS
=for html
<div class="synopsis">
B<fs diskfree> S<<< [B<-path> <I<dir/file path>>+] >>> [B<-help>]
B<fs df> S<<< [B<-p> <I<dir/file path>>+] >>> [B<-h>]
B<fs di> S<<< [B<-p> <I<dir/file path>>+] >>> [B<-h>]
=for html
</div>
=head1 DESCRIPTION
The B<fs diskfree> command formats and displays information about the
partition that houses the volume containing the specified directory or
file, including its size and how much space is currently used.
To display information about the volume itself, use the B<fs examine>
command. The B<fs examine> and B<fs quota> commands also display
information about a volume.
=head1 CAUTIONS
The partition-related statistics in this command's output do not always
agree with the corresponding values in the output of the standard UNIX
B<df> command. The statistics reported by this command can be up to five
minutes old, because the Cache Manager polls the File Server for partition
information at that frequency. Also, on some operating systems, the B<df>
command's report of partition size includes reserved space not included in
this command's calculation, and so is likely to be about 10% larger.
=head1 OPTIONS
=over 4
=item B<-path> <I<dir/file path>>+
Names a file or directory that resides on the partition about which to
produce output. Partial pathnames are interpreted relative to the current
working directory, which is also the default value if this argument is
omitted.
=item B<-help>
Prints the online help for this command. All other valid options are
ignored.
=back
=head1 OUTPUT
The output reports the following information about the volume and
partition that houses each file or directory:
=over 4
=item Volume Name
The name of the volume.
=item kbytes
The partition's total size in kilobytes.
=item used
The number of kilobytes used on the partition.
=item avail
The number of kilobytes available on the partition.
=item %used
The percentage of the partition's total space that is used (the C<used>
statistic divided by the C<kbytes> statistic, times 100).
=back
If the C<%used> statistic is greater than 90%, it is marked with the
string C<<< <<WARNING >>> at the right margin.
If the volume is a read-only volume, the output includes information about
only one of the partitions that houses it, generally the one on the file
server machine with the lowest preference rank. To verify which machine
the output is referring to, use the B<vos listvldb> command to list the
volume's locations, and the B<vos partinfo> command to display the size of
each one.
=head1 EXAMPLES
The following example shows the output for the partitions housing the
volumes C<user.smith> and C<sun4x_56.bin>:
% fs diskfree -path /afs/abc.com/usr/smith /afs/abc.com/sun4x_56/bin
Volume Name kbytes used avail %used
user.smith 4177920 3841258 336662 92% <<WARNING
sun4x_56.bin 4423680 3174500 1249180 72%
=head1 PRIVILEGE REQUIRED
The issuer must have the C<l> (lookup) permission on the ACL of the root
directory of the volume that houses the file or directory named by the
B<-path> argument, and on the ACL of each directory that precedes it in
the pathname.
