Hmm, with.exp and settings.exp both pass for me.  Could you try the
users/palves/cli-options branch?  It contains the latest version,
including the change below.

Sounds good to me, with a change to switch to active voice, to go
with the "changeable" -> "you can change" tweak in the previous round.

Like:

(gdb) help with 
Temporarily set SETTING to VALUE, run COMMAND, and restore SETTING.
Usage: with SETTING [VALUE] [-- COMMAND]
Usage: w SETTING [VALUE] [-- COMMAND]
With no COMMAND, repeats the last executed command.

SETTING is any setting you can change with the "set" subcommands.
E.g.:
  with language pascal -- print obj
  with print elements unlimited -- print obj

You can change multiple settings using nested with, and use
abbreviations for commands and/or values.  E.g.:
  w la p -- w p el u -- p obj
(gdb) 

WDYT?
