Re: pager changed after upgrade from woody to sarge:

Bob,

you're right.  after trying the 'ps -efH', i can
verify that bash is using the built-in pager and not
/bin/more.

my /etc/inputrc (without comments) is:
  set input-meta on
  set output-meta on
so, i don't think my readline configuration is the
cause.

just curious, what version(s) of bash and libreadline
do you have installed on your sarge machine.  i have
    bash (version 2.05b-26)
    libreadline4 (version 4.3-11)
    libreadline5 (version 5.0-10)

thanks.
