That while I was trying to understand what was going on, during a call
to `calendar' the value of mark-diary-entries-in-calendar had
unexpectedly changed from t to nil, so that I the #include'd file were
not read the next time `calendar' was called.  I don't know why it
happened, all I know is _that_ it happened, because I had to reset the
variable to get the entries in the calendar again.  In some functions,
the value is changed, but I do not understand how they can affect the
final value.

I recollect that after I evaluated the function, the function finished
very quickly, without problems, but it only printed the message
"Marking diary entries..." once, which - as I later found out - means
that the included files are not read.  I have not been able to
reproduce this now.

See above.  There is no dependency.

I tried both (first the function, later the file), but unfortunately I
cannot reconstruct what I did precisely.

Indeed.
