41075fb50a GF shell: restore the eh command to working order and document it
Also, when the command line parser fails, append the problematic command line
to the error message "command not parsed".

87e64a804c GF Shell: refactoring for improved modularity and reusability:
+ Generalize the CommandInfo type by parameterizing it on the monad
  instead of just the environment.
+ Generalize the commands defined in
  GF.Command.{Commands,Commands2,CommonCommands,SourceCommands,HelpCommand}
  to work in any monad that supports the needed operations.
+ Liberate GF.Command.Interpreter from the IO monad.
  Also, move the current PGF from CommandEnv to GFEnv in
  GF.Interactive, making the command interpreter even more generic.
+ Use a state monad to maintain the state of the interpreter in
  GF.{Interactive,Interactive2}.

10e7bacbfd Factor out common code from GF.Command.Commands and GF.Command.Commands2
Created module GF.Command.CommonCommands with ~250 lines of code for commands
that do not depend on the type of PGF in the environemnt, either because they
don't use the PGF or because they are just documented here and implemented
elsewhere.

TODO: further refactoring so that documentation and implementation of
*all* commands can be kept together.
