   |  Great.  I have found the report: from 2014-01-04.  ^.^
 
 We are gardually cleaning up the reported problems....
 
 gradually!
 
   |  This is really not easy for me, so much download.
 
 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.
 
 Otherwise I'll wait a bit in case there any other reported issues, and
 then close this.
 
   |  I have seen NetBSD now follows No. 1 regarding context revelation:
   |  
   |    #?1[steffen@essex ]$ alias a=b
   |    #?0[steffen@essex ]$ alias b='echo c'
   |    #?0[steffen@essex ]$ a
   |    c
 
 This much could be from the NetBSD sh, but
 
   |    #?0[steffen@essex ]$ command -v a
   |    alias a='b'
   |    #?0[steffen@essex ]$ command -V a
   |    a is aliased to `b'
 
 that isn't, that looks like bash.
 
 What NetBSD sh (from HEAD) does is ...
 
 [jinx]$ command -v a
 b 
 [jinx]$ command -V a
 a is an alias for: b 
 
 
   |  May i suggest going one step further for this interactive thing,
 [...]
   |    a -> b -> 'echo c'
 
 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).
 
   |  Ciao from midsummer Germany,
 
 I was once told that "ausweidersehen" was inappropriate for a
 phone call, and I'd guess "ausweiderhoeren" is just as
 inappropriate for an e-mail, so "ausweiderbreifen" ???
