The above is an artifact of printf-style formatting having been
retrofitted to G_warning() etc. Unsurprisingly, no-one went to the
trouble of fixing every single usage at that time ;)

Please fix this, e.g.:
G_warning(
!G_find_cell(real_name, real_mapset)
? _("Unable to read header file for raster map <%...@%s>. It is
a reclass of raster map <%...@%s> which is missing.")
: _("Unable to read header file for raster map <%...@%s>. It is
a reclass of raster map <%...@%s> whose header file can't be opened."),
name, mapset);
I don't think that mentioning it on Trac is particularly helpful, as
no-one will find it unless they're specifically looking for it, in
which case they probably already know. But it's worth mentioning here,
and probably on the Wiki (if it isn't already):
The translation macro _(...) must be applied to entire messages, not
fragments. Code such as the above needs to be fixed to have the entire
message as a single string before it can be internationalised.
