[patch #3286] printf "%c" (integer) outputs first digit instead of a character

[Eric Blake]

Update of patch #3286 (project coreutils):

                  Status:                    None => Invalid

Follow-up Comment #1:

POSIX requires the current behavior, where the argument that matches up to %c
is treated as a string and the first character of that string is printed.  So,
unfortunately, your patch cannot be accepted without violating POSIX semantics
for printf(1).  What would be useful, however, is a documentation patch that
makes this behavior clear in both the info pages and the --help output (right
now, the info pages assume that you already know how printf(3) works, which is
not as useful as it could be; and fails to mention that %c parses its argument
as a string and not a C constant integer).  I'm leaving this patch open as a
reminder that a doc patch is needed.
