The number of people has been steadily increasing who read our source
code with an editor that thinks tab stops are 4 spaces apart, as
opposed to the traditional tty-derived 8 that the PuTTY code expects.
So I've been wondering for ages about just fixing it, and switching to
a spaces-only policy throughout the code. And I recently found out
about 'git blame -w', which should make this change not too disruptive
for the purposes of source-control archaeology; so perhaps now is the
time.
While I'm at it, I've also taken the opportunity to remove all the
trailing spaces from source lines (on the basis that git dislikes
them, and is the only thing that seems to have a strong opinion one
way or the other).
Apologies to anyone downstream of this code who has complicated patch
sets to rebase past this change. I don't intend it to be needed again.
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.
