Landon Curt Noll a31078bbec Remove all RCS @(#) lines and RCS strings
Some folks might think: “you still use RCS”?!?  And we will say,
hey, at least we switched from SCCS to RCS back in … I think it was
around 1994 ... at least we are keeping up! :-) :-) :-)

Logs say that SCCS version 18 became RCS version 19 on 1994 March 18.

RCS served us well.  But now it is time to move on.   And so we are
switching to git.

Calc releases produce a lot of file changes.  In the 125 releases
of calc since 1996, when I started managing calc releases, there
have been 15473 file mods!

NAME
strncpy - copy a number of chracters from head or all of a stringr
to head or all of a string
SYNOPSIS
strncpy(s1, s2, n)
TYPES
s1 string
s2 string
n nonnegative integer
return string
DESCRIPTION
Let n1 = size(s1), n2 = size(n2), and m = min(n1, n2, n).
This function replaces the first m characters of s1 by the first
m characters of s2, and if min(n1, n) > n2, replaces the next
min(n1,n) - n2 characters of s1 by '\0'. The size of s1 and any
later characters of s1 are unchanged. The function returns s1, with
new value.
EXAMPLE
strncpy("abcdef", "xyz", 0) == "abcdef"
strncpy("abcdef", "xyz", 1) == "xbcdef"
strncpy("abcdef", "xyz", 2) == "xycdef"
strncpy("abcdef", "xyz", 3) == "xyzdef"
strncpy("abcdef", "xyz", 4) == "xyz\0ef"
strncpy("abcdef", "xyz", 5) == "xyz\0\0f"
strncpy("ab", "xyz", 3) == "xy"
LIMITS
