Replace __ with . as the module qualifier symbol.
Replace references to io.state with just io.
Replace DCGs with state variables.
Replace (C->T;E) syntax for if-then-elses with (if C then T else E) syntax.
Replace if-then-elses with switches when possible and where this does not
affect what is being tested.
Replace separate pred and mode declarations with predmode declarations.
Put predicate and function declarations just before the definition
of the predicate or function.
Delete unneeded module qualifications on predicate and function declarations
and definitions.
Update .exp files (and if needed, .inp files) for the line number changes
that result from the above.
For tests that have more than one .exp file and where one of those files
is affected by the above, add a section to the source file header that says
which .exp file is for what grade, with XXXs for the (as yet) unknown parts.

Make these tests use four-space indentation, and ensure that
each module is imported on its own line. (I intend to use the latter
to figure out which subdirectories' tests can be executed in parallel.)
These changes usually move code to different lines. For the debugger tests,
specify the new line numbers in .inp files and expect them in .exp files.

Branches: main
Add a new mdb command, 'shell', that allows users to execute shell commands
from within the debugger.
Allow the user to give up to nine additional arguments to the 'source' command.
Occurrences of the strings "$1" through "$9" in the sourced file are replaced
by the corresponding additional arguments, allowing for parameterised scripts.
Use the two new features mentioned above to add two more mdb commands: one
to open a term, goal or exception in an external editor another command
to perform a grep on a term, goal or exception (useful for seeing if a value
occurs in a big map, for example).
