Subject: Bug#161286: indent: texinfo2man's argv handling is fragile

Package: indent
Version: 2.2.8-1
Severity: normal
Tags: sid

The texinfo2man utility included in indent tends to crash when less than two
arguments are specified on the commandline.  The app's main() simply does
this:

    in = fopen (argv[2], "r");
    process_texi (in);
    fclose (in);

This will happily dereference argv[2] whether it exists or not, then assume
the fopen proceeded and try to read from a quite possibly closed FILE*.  A
few lines later it does so again with argv[1].

If texinfo2man is actually to be provided to users, it should (a) be able to
survive unpredictable commandlines, and (b) be able to print its commandline
usage.  That said, I'm not clear what it's doing in the indent binary
packages anyway.
