tests/make: replace 'variable expression' with 'expression'

Each expression is based on a variable, there's no need for the
verbosity. The wording in make's diagnostics will be changed in a
follow-up commit.

tests/make: force line-based diagnostics to be listed in the tests

This way, contradictions between the intended output and the actual
output are closer together and have a better chance of being spotted.

tests/make: test very small and very large numbers in conditions

make: clean up nitpicks

In ParseWord, the expressions '*p' and 'ch' are the same.

In ParseDependencyTargetWord, clean up a wordy comment and join two
conditions.

In the test cond-token-number, clarify that make doesn't convert from
hex to decimal but only from hex to internal representation.

No functional change.

make: clean up comments

make(1): add remarks to the tests about conditions

make(1): add test for hexadecimal numbers in conditionals

make(1): add tests for numbers in conditions

make(1): describe the purpose of each newly added unit test dummy

make(1): add dummies for fine-grained tests, one per single feature

The test names have been derived from the current manual page.

All these tests are dummies right now, and the code from the existing
tests will be moved into the new tests step by step.

This is done to prevent modmisc, escape, varmod-edge and varmisc from
growing without any bounds, and to reduce the side-effects of one test
to the others.
