Hi Julia,

I would like to loop you in here because you have helped us with
Coccinelle questions in the past.

The task at hand is to identify calls to the macro `OPT_CMDMODE()` (and
other, similar macros) that get a fourth argument of the form

	N_("<some string>")

The problem is to identify `<some string>` that ends in a `.` (which we
want to avoid) or that starts with some prefix and a colon but follows
with an upper-case character.

In other words, we want to suggest replacing

	N_("log: Use something")

or

	N_("log: use something.")

by

	N_("log: use something")

Ævar suggested that Coccinelle can do that. Could you give us a hand how
this would be possible using `spatch`?

Thank you,
Johannes
