sk_startup and sk_nextaddr are entirely internal to winnet.c; nearly
all of import.c and minibidi.c's internal routines should have been
static and weren't; {read,write}_utf8 are internal to charset/utf8.c
(and didn't even need separate declarations at all); do_sftp_cleanup
is internal to psftp.c, and get_listitemheight to gtkdlg.c.
While I was editing those prototypes anyway, I've also added missing
'const' to the 'char *' passphrase parameters in import,c.
Ilya Shipitsin sent me a list of errors reported by a tool 'cppcheck',
which I hadn't seen before, together with some fixes for things
already taken off that list. This change picks out all the things from
the remaining list that I could quickly identify as actual errors,
which it turns out are all format-string goofs along the lines of
using a %d with an unsigned int, or a %u with a signed int, or (in the
cases in charset/utf8.c) an actual _size_ mismatch which could in
principle have caused trouble on a big-endian target.
does UTF-8 copy and paste (falling back to normal strings if
necessary), it understands X font encodings and translates things
accordingly so that if you have a Unicode font you can ask for
virtually any single-byte encoding and get it (Mac-Roman pterm,
anyone?), and so on. There's work left to be done (wide fonts for
CJK spring to mind), but I reckon this is a pretty good start.
