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.
Now that all the call sites are expecting a size_t instead of an int
length field, it's no longer particularly difficult to make it
actually return the pointer,length pair in the form of a ptrlen.
It would be nice to say that simplifies call sites because those
ptrlens can all be passed straight along to other ptrlen-consuming
functions. Actually almost none of the call sites are like that _yet_,
but this makes it possible to move them in that direction in future
(as part of my general aim to migrate ptrlen-wards as much as I can).
But also it's just nicer to keep the pointer and length together in
one variable, and not have to declare them both in advance with two
extra lines of boilerplate.
malloc functions, which automatically cast to the same type they're
allocating the size of. Should prevent any future errors involving
mallocing the size of the wrong structure type, and will also make
life easier if we ever need to turn the PuTTY core code from real C
into C++-friendly C. I haven't touched the Mac frontend in this
checkin because I couldn't compile or test it.

which to pipe printed data. Of course by default printing is
disabled; typically cfg.printer would be set to `lpr', perhaps with
some arguments.

The current pty.c backend is temporarily a loopback device for
terminal emulator testing, the display handling is only just enough
to show that terminal.c is functioning, the keyboard handling is
laughable, and most features are absent. Next step: bring output and
input up to a plausibly working state, and put a real pty on the
back to create a vaguely usable prototype. Oh, and a scrollbar would
be nice too.
In _theory_ the Windows builds should still work fine after this...
