@make: add ":" to error message about unknown modifier

In the manual page, the modifiers are listed with a preceding ":", so
use the same pattern in the error message. This removes an inconsistency
between the error messages "Unknown modifier" and "Bad modifier".

@make: in stack traces from target commands, add the command level

A target can contain several commands, and these commands are likely to
contain the same expressions. To distinguish them, add one more line to
the stack trace, to narrow down the source of the error.

@make: reduce line length in error messages

The error messages for deeply nested parse errors were hard to decipher,
due to the large amount of text.  Split these messages into individual
lines, just as in the backtrace for .include files and .for loops.  This
unified backtrace makes the output more uniform.

@make: don't run erroneous commands in compat mode

When there is a parse or evaluation error in an expression that becomes
part of the command, don't run that command, as the result of the failed
evaluation typically contains garbage characters. Skip the remaining
commands from that target as well, as they may depend on the erroneous
command.

@make: error out on parse/evaluation errors in shell commands

The expression ${VAR:X} has an unknown modifier ':X'.  Previously, this
expression errored out when the expression was evaluated at parse time,
but not when the expression was evaluated when generating the commands
to bring a target up to date.  The errors were previously reported, they
didn't affect the exit status, though.

Now, errors in expressions are handled in the same way, regardless of
the time at which they are evaluated.

@make: improve error message for unknown modifier

Back in 1995, the modifiers were all single-character, and it made sense
to print only the first character.  Nowadays, with ':S', ':@@var@@...@@',
'::=' and several others, a little more context is useful to see where
the exact error is.  The actual modifier is still guessed, and the guess
may be wrong as soon as backslashes get involved, but it is still better
than before.

@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.
