Make sure that each va_start has one and only one matching va_end,
especially in error cases.
If the va_list is used multiple times, do multiple va_starts/va_ends.
If a function gets va_list as argument, don't let it use va_end (since
it's the callers responsibility).

Heimdal/krb4/KAME changes already fed back, rest to follow.
Inspired by, but not not based on, OpenBSD.
properly together. xxgdb communicates with a gdb running on a pty
that it sets to -echo,-onlcr prior to forking the gdb process.
GNU readline preserves the -echo setting while libedit was undoing it
(setting the tty to a sane state and totally confusing xxgdb's parser).
this diff simply disables libedit if both readline emulation and
"stty -echo" are used/set. that is enough to make xxgdb work once
again, but (XXX) this is not how GNU readline handles stty -echo (it
does not echo anything, but editing commands like ^A,^K, etc.
still work), so the readline emulation isn't perfect.
change reviewed by christos.
I wrote for tcsh(1) three years ago.
- implement EL_RPROMPT, which allows a setting/getting of a function which
returns a string to be used as the right-side prompt.
- improve HISTORY and AUTHORS sections in editline(3).
- bump shlib minor version for EL_RPROMPT.
XXX: due to an implementation issue, the rprompt has a 1 space gap before the
edge of the logical screen. editline's logical screen is 1 space less
than the full screen width, so there's a 2 space gap between the rprompt
and the right end of the physical screen. i'm not concerned about this.
- don't reopen fp if it was successfully opened in a previous check
- use strlcpy()/strlcat() instead of snprintf() to build a pathname,
since the former are more portable to other systems than the latter
* whitespace fascism
* implement el_get(EditLine *, int op, void *result), which does the
inverse of el_set()
* add EL_EDITMODE operation to el_set and el_get; if non zero editing
is enabled (the default).
* add "edit on | off" editrc command, which modifies EL_EDITMODE.
users can now add '*:edit off' in ~/.editrc as an advisory to
disable editing.
NOTE: at this time EL_EDITMODE is just an indication of the
state of the 'edit' command. It's up to the application to check
this after el_source() or el_parse() to determine if editing is still
required.
