bug#1092: compilation-goto-error goes to wrong location when buffer has hidden regions

[Peter Sanford]

I have the copyright region at the head of my files hidden using 
selective-display and ^M. When this region is hidden functions like 
compilation-goto-error jump to the wrong location: n lines below the 
correct location where n is the number of hidden lines. If I use 
goto-line and the line number reported in the compilation buffer, emacs 
takes me to the correct line.

When the region is visible everything works as expected.
