OK.  Minor nit: Please avoid overlong git commit messages (i.e., not
longer than 78 characters).  And there should be an empty line after
the first line to help tools like `gitk` to properly display git
commits.  [Overlong lines should be avoided in the C code, too, both
for comments and code.]

This is certainly helpful.  However, it doesn't need to be complete
right now, but it should cover a good share of languages that use the
Latin script.  BTW, please add a comment to the `adjustment_database`
array, explaining the format.

Sounds good, thanks.  I also request you to produce a 'final' GSoC
tree with cleaned-up commit messages, as mentioned in other e-mails to
this list to other GSoC participants.

Excellent!  I think it would also be beneficial if you could mention
your findings in either a git comment or in the code itself, together
with some real-world examples of such quirks (i.e., font name, font
version, glyph name, reason why it fails, etc., etc.)
