[Ecls-list] Warnings should print contexts

[Gabriel Dos Reis]

Hi,

In ECL-0.9l (and trunk), a compiler warning will not print the current
form being
compiled, even thought (print-current-form) is called.  That renders
the warnings almost useless when *suppress-compiler-notes*.

(print-current-form) should print something if (warn) thinks it is
going to print something.

So, I propose that (print-current-form) either takes a verbosity argument
or shuts up only if all of *compile-verbose*, *suppress-compiler-warnings*,
*suppress-compiler-notes* are false.

Opinions?
