[Bug-indent] fix for texinfo2man.c (fwd)

[Santiago Vila]

Hello.

In Debian Bug#132399 (see http://bugs.debian.org/132399) Matt Kraai reports:

  The indent manual page uses \' instead of '.  This is rendered as
  an accent, =B4 (0xb4), which displays as a solid box on my console.
  It only needs to be escaped when it comes at the start of the
  line, and the appropriate way to escape it is by preceding it with
  a \& (a zero-width space).

Well, I have received a patch from Peter De Wachter <address@hidden>
to fix this bug. Quoting Peter:

  Hi, I was browsing the help-tagged bugs and this one looked not too
  hard. It turns out finding good documentation on groff is not that easy
  at all :) but according to #120306 \(oq and \(cq should be used for left
  and right single quotes, and the attached patch makes texinfo2man.c do
  that.

This is the patch:

   putchar (c);
   at_start_of_line = at_start_of_line_for_dot = (c == '\n');


I plan to apply it to the Debian indent package. Could it be included
in indent-2.2.10?

Thanks.
