In the end, that code isn't even needed.  If no mixed-uuencode
option has been specified, then the default is "mixed" anyway.
The state of WHICH_OPT_MIXED_UUENCODE detects any of the four
states ("0" being the default/unspecified state):

I'll have to fix the doc.  It inhibits compression only.
It says nothing about the decision to encode.  The default
is mixed

The operative phrase here is "Compressed files are never processed as plain 
text."
says only that if you compress, then you uuencode.  If you compress all files,
then you uuencode all files, too.  How's this:

Immediately above the switch statement above is this code:

Suggestions welcome :)

OK, I think _my_ eyeballs jumped.  Sorry.  I think this is adequate for this 
use here,
but should probably be derived from another variation on the quoting style 
names:

I was using "shell_quoting_style" and we need "windows_cmd_quoting_style".

Done:

  {
    static char ftime_fmt[] = "%Y-%m-%d %H:%M %Z";

    /*
     * All fields are two characters, except %Y is four and
     * %Z may be up to 30 (?!?!).  Anyway, if that still fails,

    char buffer[sizeof (ftime_fmt) + 64];
    time_t now;
    struct tm * local_time;
    time (&now);
    local_time = localtime (&now);
    {
      size_t l =
        strftime (buffer, sizeof (buffer) - 1, ftime_fmt, local_time);
      if (l == 0)
        {
          ftime_fmt[sizeof(ftime_fmt) - 2] = 'z';
          l = strftime (buffer, sizeof (buffer) - 1, ftime_fmt, local_time);
        }
      if (l > 0)
        fprintf (fp, made_on_comment_z, buffer, OPT_ARG(SUBMITTER));
    }
