For this patch:

The version string will then automatically be wrapped if the terminal 
width is too narrow.

For the whole series in general:

The reason I started doing this, was so there could be nice html output 
in hg serve help, generated by running docutils (or a future version of 
minirst supporting outputting to html) on the restructured text output. 
The generated restructured text should then later also be possible to be 
used by gendoc.

Unifying all help texts to minirst does also ensure automatically 
fitting all help text to terminal width. Another thing is  if minirst at 
a later point support colors, e.g. coloring options in optionlists then 
the help texts will then of course also be colored, since they will go 
through minirst.
