handle.c
(interrupt): Internal linkage.
(interrupt): Use proper type for access from signal handler.
(intr): Don't increment to set, it's unobvious and it could overflow.
(main): Clarify messages.
(hostport) [_WIN32]: Remove useless conditional code.
(main): Fall back to compiled-in host only if environment doesn't
supply one, not if it can't be resolved. Same for port.
strings bytewise unless the stream is buffered. Switch stdout to
line-buffered mode.
(login): Explicitly flush stdout, because Windows doesn't implement
line-buffering faithfully.
(login): New parameter utf8. If set, request option utf-8 from
server.
(expect, recvline): Split recvline() out of expect(). Replace or
remove some unhelpful diagnostics.
(eight_bit_clean): New.
(screen): If eight_bit_clean is set, highlighting is switched with
SO/SI. Else characters with MSB set are highlighted.
(main): New option -u to request UTF-8 and set eight_bit_clean.
Get it from environment variable LOGNAME if set,
else get the user name from the system.
(main) [_DWIN32]: Add stdin redirection ability to the Win32 port.
The client reads until stdin redirection empty and then terminates.
linkage that is not in any other header in misc.h. Remove some
redundant declarations elsewhere.
(prompt, doredir, dopipe, doexecute, output, screen, parsedelay):
Static linkage.
thread entrypoints:
(lwpSelect, shutdown_sequence): Parameters didn't match thread entry
point prototype.
(lwpEntryPoint): Arguments didn't match thread entry point prototype.
Change linkage of functions without prototype declaration to static
where possible.
Remove some superflous declarations, replace others by suitable
includes.
breaks the fd_set abstraction, and works only with the traditional
Unix implementation of fd_set. Use fd_set and its operations instead.
Remove unused source files.
effect. Replace calls by struct assignment where possible. Replace
clear buffer, copy string to buffer by strncpy(). Use assignment to
clear when that's clearer. Replace overlapping copy through bounce
buffer by memmove(). Replace rest by standard memset() and memcpy().
Also use sizeof() instead of literal array sizes for robustness, and
instead of symbolic array sizes for clarity.
