Gabor Kelemen 59793d67d4 Make helpcompiler more verbose on dot ahelps
Currently we get a warning if the ahelp is one dot
and there was no previous bookmark tag.

This warning contains only the text with the problemmatic ahelp.

It would make it easier to hunt down such problems if we would
know the file names.

This patch does that, and now I see 334 problems in 137 files.
