objects/FS/function.c contains a lot of single verbs marked for translation.

The problem is that these verbs are not at all easy to translate in many
cases because there is not enough context, and looking at the immediate
source reference does not help either. As an example, "Add" translates into
two swedish expressions; "Lägg till" and "Addera". "Lägg till" is used in
general for adding something, "Addera" is reservered for the mathematical
function. Currently, I have no idea which one to use because there is
simply no hint that either is correct in the functions.c case, and I can't
figure it out just by having a simple look at the source.

One simple help would be if simple comments were added at the preceding
lines. They wouldn't have to be more than one line, just enough to
understand the context of how the verb is used. Like this:

     /* Translators: Mix something with something else */
     {N_("Blend"),              3, function_insert_verb },
     /* Translators: Add two numbers together */
     {N_("Add"),                3, function_insert_verb },

The trick here is that if a comment is placed on the line immediately
preceding a gettext-marked comment, xgettext will put this comment next to
the message in the po file too, thus giving the translator a direct hint on
the context when translating.
