Problems formatting options in man page

I'm trying to have my cake and eat it too. Perhaps someone here can help
with that quest.

I have a script. When run with the -h flag it emits the script's doc string
formatted using rst. I want to process that output into man pages (using
rst2man). For the most part, that works just fine. But I'm having trouble
seeing how I'm supposed to indent multi-line descriptions of the script's
command line flags.  Here is the OPTIONS section of the doc string:

OPTIONS
=======

-f x,y[,axis[,color[,legend[,style[,marker]]]]] plot field x vs. field y
-b x,y,val,c set background to c where field y value >= val at x
-p file    if given, will save the plot to the named file and exit.
-F fmt     plot the X axis using fmt (default varies)
-s sep     use sep as the field separator (default is comma)
-d dimension specify dimensions in (I think) inches, default 8 wide, 6 high
-T title   set title of the plot
-r label   set the label for the right y axis
-l label   set the label for the left y axis
-x label   set the label for the x axis
-H         skip header at start of input
-L         do not create a legend
-Y min:max[,min:max] set the initial min and max values for the left (and
           optionally, right) Y axis

That last line is the problem. I generate my man page using this make
recipe:

python $< -h 2>&1 | rst2man \
| sed -e '/^\.de1 rstReportMargin/,/^\.\./d' \
     -e '/^\.de1 INDENT/,/^\.\./d' \
     -e '/^\.de UNINDENT/,/^\.\./d' \
| egrep -v '^\.(UN)?INDENT' > $@

The sed and grep commands are just a little cleanup. The problem is with
rst2man. It complains:

<stdin>:40: (ERROR/3) Unexpected indentation.

It appears it is complaining about the second line of the -Y description.
Is there some way to format this section so when simply spit to
stdout/stderr it reads okay (no lines greater than 80 columns), yet passes
muster when fed to rst2man?

Thx,

Skip
