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.
character set configuration to UTF-8, on both Windows and Unix, and
reorganise the dropdown lists in the Translation menu so that UTF-8
appears at the top (and Unix's odd "use font encoding" is relegated to
the bottom of the list like the special-purpose oddity it is).

implementations of libcharset, since we've had at least one request for
it in PuTTY.
