Ablity to render CHM when there is no TOC/.hhc file present:

In the example above all of the HTML (i.e. the actual content) files can be found in the ‘gca’ directory .

Note that the default Windows application, HH.exe has no problem working with the files our customer has provided, so we know the files to be otherwise sound as far as the core CHM structure is concerned.

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
