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.

Fix a problem reported by Ian: the debugger ignored information about the head
variables of the predicates generated by the compiler from lambda expressions
because they didn't have names.
compiler/hlds_pred.m:
Add a predicate to ensure that all headvars have names.
compiler/lambda.m:
Call that predicate to give names to the predicates created from lambda
expressions.
compiler/code_gen.m:
Call that predicate to give names to the predicates created from lambda
expressions, in case other transformations also create predicates
with unnamed head variables.
doc/user_guide.texi:
Add a new mdb command, var_details, and a new method of invocation of
an existing mdb command, flag. I used them to track down this bug.
trace/mercury_trace_internal.c:
Implement the var_details mdb command, and the new method of invocation
of the flag command.
trace/mercury_trace_vars.[ch]:
Add a function to print variable details.
tests/debugger/mdb_command_test.inp:
Test the documentation of the new command.
tests/debugger/completion.exp:
Expect the new command.
tests/debugger/lambda_expr.{m,inp,exp}:
Add the new test case to test for the bug.
tests/debugger/Mmakefile:
Enable the new test case.
