Aditya, of course, if you can detect and come across some unintended
'/**' comments in some files, clean them in the same go (as you did
with ecryptfs).

I am just worried that if you extend it to the fully generic case,
that the list of cases simply explodes: showing many 1,000 cases
across various 1,000 files that need to be cleaned up, and such
clean-up work is just too much to get done by yourself.

The current list limited to comments in header lines seems to be a set
of patches that you can probably get done.
