depend2.am: fix comments on verbosity of compilation rules
The situation and decisions described on those comments have become quite outdated since the introduction of the silent-rules support. Today, the general idea is to have nice, terse output if silent rules are enabled, and complete, faithful, very verbose output if they are not -- without trying to "massage" this verbose output in a more pleasant form if that would cause complication in the affected code. So it's better to just drop the obsolescent comments. Note that we don't start simplifying the existing rules according to this new philosophy; that will only be done when touching some existing code (for the 'depend2.am' code, that will probably happen on the master branch).

-## Verbosity of FASTDEP rules
-## --------------------------
-## (1) Some people want to see what happens during make. They think
-## @-commands are evil because hiding things hinders debugging.
-## (2) Other people want to see only the important commands--those that
-## may produce diagnostics, such as compiler invocations. They
-## do not care about build details such as dependency generation
-## (the if/then/else machinery in FASTDEP rules). Their point is
-## that it is hard to spot diagnostics in a verbose output.
-## (3) Other people want "make -s" to work as expected: silently.
-## This way they can spot any diagnostic really easily.
-##
-## The second point suggests we hide rules with @ and that we 'echo'
-## only the relevant parts. However this goes against the two others.
-## There are regular complaints about this on the mailing list, but
-## it's hard to please everybody. On April 2003, William Fulton (from
-## clan (3)) and Karl Berry (from clan (2)) agreed that folding the
-## compile rules so that they are output on a single line (instead of 5)
-## would be a good compromise. Actually we use two lines rather than one,
-## because this way %SOURCE% is always located at the end of the first
-## line and is therefore easier to spot. (We need an extra line when
-## depbase is used.)
