Found two multiple evaluation macros. One of them so long and scary it
too many people to unravel correctly and place into a static function.
While here, move the flags bits into local variables, which reduces
the amount of () in the checks.

Wrap <vis.h> so that calls go direct and the symbols are all weak

Add VIS_DQ to escape double quotes. OK deraadt@ semarie@ reyk@

Add stravis(), an allocating version of strvis(). OK doug@

Fix handling of VIS_ALL: in vis(), actually encode all characters
as requested and give a correct estimate when they don't all fit,
and in unvis() decode them instead of erroring

ok nicm@, deraadt@

backout VIS_HEX. guenther@ points out that the C89 \xff encoding
idiotically accepts more then two hex digits following the \x, even
on platforms where a char has 8 bits. It is therefore dangerous to have
an almost-bit-not-quite compatible format in vis(3).

The VIS_ALL (encode all characters) option introduced in the same commit
remains.

Two new flags: VIS_ALL - encode all characters, not just invisible ones
and VIS_HEX - use C89 \xff style hexadecimal encoding.

Teach unvis(3) how to deal with the hex encoding.

repair VIS_GLOB; deraadt@ otto@ OK

Remove spurious call to isgraph() that sneaked in in rev 1.16.
ok millert@ deraadt@

Fix the VIS_GLOB checks added in rev 1.16
Add missing casts to u_char so 0xff is treated the same on machines
with signed and unsigned chars.
OK deraadt@ espie@

Add VIS_GLOB to escape special characters used by shell-style globbing.
From Solar Designer based on changes in FreeBSD. OK deraadt@

zap remaining rcsid.

Kill old files that are no longer compiled.

okay theo

deregister (and deauto!). ok millert@ marco@

ansify function definitions and zap some `register'

ok millert@

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

sync vis() behaviour when VIS_SAFE to man page: don't do anything if isgraph()
is true, even if the character isn't 7-bit.

need string.h

Fix strnvis(): don't truncate unnecessarily, set the return value correctly
if we had to truncate, and don't NUL-terminate if size == 0.

We live in an ANSI C world. Remove lots of gratuitous #ifdef __STDC__ cruft.

Explicitly NUL terminate dst in strvis() and strvisx() in case
we are passes an empty string. vis() and strnvis() were already OK.
Based on patch by wilfried@openbsd.org

Add strnvis(3) -- a length-bounded version of strvis(3) with a return
value similar to snprintf(3) and strlcpy(3).

off-by-one calculation error; getcwd() would return NULL if the buffer was
the needed length + terminating byte + 1; that 1 is not needed; assar

#if __STDC__ --> #ifdef __STDC__

Clean up some -Wall complaints.

Fix RCS ids
Make sure everything uses {SYS,}LIBC_SCCS properly
