No, we concluded that if there were no reasonable way of doing that,
we should use an i18n comment to have the context explained in
gdb.pot, where the translators will see it.  Which is what I mentioned
as a fallback above.

Yes, I understood that much.

How about rewriting the code so it'll produce something like

  Note: breakpoint(s) 1-9, 10-15, 21, 42 also set at pc 0x439ee0.

?

Then we could have the variable list of breakpoint numbers produced
as a string, and output that string with a format such as this:

  "Note: breakpoint(s) %s also set at pc 0x%x."

Actually, this would work for i18n even if we don't produce ranges of
numbers but a plain "1, 2, 3, 4, ..." list, but ranges would compress
some overly-long lists.

The `disabled' notification could be printed as a separate message.
For example:

  Note: breakpoint(s) 1-9, 10-15, 21, 42 also set at pc 0x439ee0.
  Note: breakpoint(s) 3, 11, 21 are disabled.

We could do something similar with "(thread %d)", for example produce
a separate message for each thread.  I think that the current format
becomes quite unreadable anyway when too many "disabled" and "thread
N" parts are produced.

WDYT?
