[tex-live] Oddities with tlmgr generate

[Ruben Prins]

Having tried calling 

  tlmgr generate updmap

to no avail on my Windows XP machine (I think the Windows part is relevant),
and digging into the tlmgr code, I think I have found a bug in the kpsewhich
function in TLUtils.pm:

sub kpsewhich {
  my $var = shift;
  my $ret = `kpsewhich -var-value='$var'`;
  chomp ($ret);
  return $ret;
}

should probably read

sub kpsewhich {
  my $var = shift;
  my $ret = `kpsewhich -var-value=$var`;
  chomp ($ret);
  return $ret;
}

Note the missing single quotes. If the single quotes are present, kpsewhich
returns nothing (at least on Windows). 

The generate action is the only part of tlmgr.pl that seems to call the
kpsewhich function; the rest uses `kpsewhich -var-value=XYZ` directly
(without the quotes).

Also, to me the place of the --dest and --localcfg options seems odd: 

  tlmgr generate --dest XYZ --localcfg XYZ updmap

I think 

  tlmgr generate updmap --dest XYZ --localcfg XYZ

looks a lot more obvious (and --help seems to suggest this too).
