minirst: create valid output when table data contains a newline

When table data contained a newline, the result of minirst.maketable
did not look nice plus it was not recognised by minirst.format:
  == === ====
  l1 1   one
  l2 2   2
22
  l3
  == === ====

This problem occurred when the description of options had a very long
translation which was split by newlines. Do not bother a translator with
this detail.

The multiline translations for option descriptions have been fixed in
baf1600adfbe in it.po, de.po and ro.po. I manually did the same as this patch
does, I removed the newlines.

When a newline was in the description, this created unusable help output:
  $ hg help somecommand
  hg somecommand [option]...

  with somecommand, you can...

  options:

  == =================== =======================================================
  =================================== --longdesc VALUE    xxxxxxxxxxxxxxxxxxxxxx
  xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx -n --norm
  normal desc --newline VALUE line1 line2 == =================== ===============
  ===========================================================================

now this looks much nicer:
  ...
  options:

      --longdesc VALUE xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
                       xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
   -n --norm           normal desc
      --newline VALUE  line1 line2
