'getAnywhere' crashes when its argument starts with a period:

> getAnywhere( '.onLoad')
Error in exists(x, envir, mode, inherits) : 
        invalid first argument

One fix might be to replace the line

if ( !is.null(f <- getS3method(gen, cl, TRUE))) {

with

if ( nchar( gen) && !is.null(f <- getS3method(gen, cl, TRUE))) {
