This patch is nearly ready and I will send it shortly.


While I was working on the docs aspect I noticed an infelicity in the
documentation.  It generally talk about the signal disposition that
the shell `inherits from its parent'.  For example:

  traps caught by the shell are reset to the values inherited from the
  shell's parent, and traps ignored by the shell are ignored

But this is misleading.  The values that the signals are reset to are
those which the parent inherited _at shell invocation_ (ie, at exec).
If the shell is a subshell (produced with `( )' perhaps), it may have
inherited different settings from its _parent_ (ie, the main shell).

I think this wording should be changed throughout to read `inherited
at shell invocation'.  Do you agree ?  Would you welcome a patch along
those lines ?


Thanks,
Ian.
