** Description changed:

  The option "--node" of "pinfo" is used to initially navigate to a section of 
the info page (a node),
  in the same way it is implemented in "info".
  This option is important when accessing long info pages.
  
  It could be expected that the option is compatible with "info",
  and therefore has a short form "-n". It seems like this was actually intended 
to be the case.
  
  Using the option "-n", as in
  
-     $ pinfo zsh -n Keymaps
+     $ pinfo zsh -n Keymaps
  
  fails with an error message referring to the long option "--node":
  
-     $ pinfo zsh -n Keymaps      
-     Przemek's Info Viewer v0.6.9
-     --node option used without argument
+     $ pinfo zsh -n Keymaps
+     Przemek's Info Viewer v0.6.9
+     --node option used without argument
  
  The long option works fine, in the same way it does in "info":
  
-     $ pinfo zsh --node Keymaps
+     $ pinfo zsh --node Keymaps
  
  opens the info page for "zsh", showing the section "Keymaps".
  
+ (The option "--n" does work, because it is a prefix form of the long
+ option)
+ 
+ The option "-n" is not mentioned in the documentation, which is currently 
+ correct - but most other options have a short variant.
+ 
+ 
  Another example of the options relevance:
  
-     $ pinfo coreutils --node 'tsort invocation'
+     $ pinfo coreutils --node 'tsort invocation'
  
- shows the info page of "tsort" (a node of coreutils, actually), 
+ shows the info page of "tsort" (a node of coreutils, actually),
  while using "-n" does not. Navigating manually from
  
-     $ pinfo coreutils
+     $ pinfo coreutils
  
  is not a good alternative, because the index is long.
  
  (Note that "pinfo tsort" shows the man page of "tsort", which is very
  short)
