  ||  Great.  I have found the report: from 2014-01-04.  ^.^
  |=20
  | We are gardually cleaning up the reported problems....
  |=20
  | gradually!
 
 Of course.  I did not want to imply some kind of pressure, except
 maybe of that of my own surprise, since i had totally forgotten
 about this report.
 
  ||  This is really not easy for me, so much download.
  |=20
  | I understand.   If you have a working NetBSD (7 or more recent)
  | and you tell me which version, I can probably make you a sh binary
  | from current sh sources, to work on that system, if you'd like to try it.
  |=20
  | Otherwise I'll wait a bit in case there any other reported issues, and
  | then close this.
 
 Of course i will run NetBSD.  8.0_RC1, to be exact.  I checked out
 sh, test, kill and printf
 
   #[steffen@nbsd]$ export CVSROOT=3D"anoncvs%anoncvs.NetBSD.org@localhost:/cvsroot"
   #[steffen@nbsd]$ cvs checkout -r -P src bin/sh
   Warning: Permanently added the RSA host key for IP address '199.233.217.1=
 98' to the list of known hosts.
   cvs server: cannot find module `bin/sh' - ignored
   cvs [checkout aborted]: cannot expand modules
 
 (i got it right later..), did some "ln -s" (should have looked in
 the Makefile and set NETBSDSRCDIR), and compiled it without
 problems.  I can confirm that it works:
 
   #[steffen@nbsd]$ cd bin/
   /home/steffen/usr-nbsd-netbsd-i386/bin
   #[steffen@nbsd]$ ln -s /bin/date gcc
   #[steffen@nbsd]$ cd
   /home/steffen
   #[steffen@nbsd]$ command -v gcc
   /home/steffen/usr-nbsd-netbsd-i386/bin/gcc
   #[steffen@nbsd]$ command -pv gcc
   /usr/bin/gcc
 
  ||  I have seen NetBSD now follows No. 1 regarding context revelation:
  || =20
  ||    #?1[steffen@essex ]$ alias a=3Db
  ||    #?0[steffen@essex ]$ alias b=3D'echo c'
  ||    #?0[steffen@essex ]$ a
  ||    c
  |=20
  | This much could be from the NetBSD sh, but
  |=20
  ||    #?0[steffen@essex ]$ command -v a
  ||    alias a=3D'b'
  ||    #?0[steffen@essex ]$ command -V a
  ||    a is aliased to `b'
  |=20
  | that isn't, that looks like bash.
  |=20
  | What NetBSD sh (from HEAD) does is ...
  |=20
  | [jinx]$ command -v a
  | b=20
  | [jinx]$ command -V a
  | a is an alias for: b=20
 
 Yes, it is different:
 
   #[steffen@nbsd]$ command -V s-groff
   s-groff is an alias for: groff -dpaper=3Da4 -P-pa4=20
 
  ||  May i suggest going one step further for this interactive thing,
  | [...]
  ||    a -> b -> 'echo c'
  |=20
  | You can send in another PR (a change request) for that if you
  | like, and we'll see what people think - but I would not be inclinded
  | to go that far unless there is a real demand for it (just means a
  | bunch of extra code for an obscure feature (aliases) that should
  | probably just be removed anyway).
 
 Ok...  Ok, i realize that the NetBSD shell allows function names
 which contain a hyphen-minus.
 
  ||  Ciao from midsummer Germany,
  |=20
  | I was once told that "ausweidersehen" was inappropriate for a

  | inappropriate for an e-mail, so "ausweiderbreifen" ???

  | Ugh, memory is worse than Ieven I thought (which is saying something)

  | maybe auswiederschreiben ?
 
 Very nice!!!  I am inclined to correct an elder and wiser man in
 that it should be "auf", and yes, why not "Auf Wiederschreiben"?
 (But i never encountered this term.  "Auf Wiedersehen" and "Auf
 Wiederh=C3=B6ren" for seeing and hearing are very common still.  Even
 in Germany that is, but mind you, it will not take long and we are
 all talking English, unless a miracle happens.)

 I wish i could put some heart and soul in calligraphic Thai.
 Good bye!
