appropriate message/warning suppression

[npcooley]

Hi,

Would it it be possible to adjust how import handles messages?

I.e. wrapping rtracklayer::import(x) in either suppressMessages() or suppressWarnings() does not provide the intended silencing of import's messages.

See the following lines:

rtracklayer/src/ucsc/errAbort.c

Lines 53 to 58 in 32cd3c2

	if (format != NULL) {
	fflush(stdout);
	vfprintf(stderr, format, args);
	fprintf(stderr, "\n");
	fflush(stderr);
	}

which calls vfprintf rather than standard warning(), error(), message().
