(copy_utf8_to_ascii_no_funny): New.
(flash, wall, prmptrd, uprmptrd, getcommand): Use them to filter
input.
(uprnf, pr_flash): Use them to filter output.
(prtoascii): No longer used, remove.
(player_commands, player_commands_index): Internal linkage.
player->argp[]. Assign complete argument vector. This should make
buffer overruns blatantly obvious.
(parse): Don't bother checking SPACE argument, just crash. It is
extremely unlikely that such a programming error wouldn't be
discovered by even them most superficial testing.
that didn't set player->aborted sent the telegram, e.g. EOF.
(getele): Fix misleading size of left[].
(getele, tilde_escape): Simplify. tilde_escape() now returns the
escape code instead of comparing it to second argument.
platform is evil, and line editing is none of the server's business
anyway. If your client can't deal with the delete key, well, here's a
nickel, kid, get yourself a better computer.
string input other than through parse() or getele() failed to strip
'\r', which could end up in ship names and such.
(getele): Code dealing with '\r' is now redundant, remove. It ceased
to work in rev. 1.6 because input filtering replaces '\r' by '?'.
manually stripped off padding, which is evil. The new code does
nothing when the stdout is not connected to a terminal.
(SO, smso, SE, rmso): Rename, static linkage.
(putso, putse): New.
(screen): Use it.
(main): New option -h. Terminate unsuccessfully on invalid option.
(usage, parse_args): Factored usage() out of parse_args().
(parse_args): More useful diagnostics.
Previously, it printed how many were selected, which can include old
members of the group.
(flee, army): The rather obscure feature to assign the fleet's /
army's retreat orders to members was broken. It ignored ownership,
and thus could copy some other player's retreat orders. Abusable.
Copying the first member's retreat orders is less than useful, in
particular for group ~. The code now chooses the first one in the
same sector with RET_GROUP set. RET_GROUP is never set for group ~.
