bug#6528: 24.0.50; `read-buffer' doc string

[Christoph <cschol2112@googlemail.com>]

The only other function in minibuf.c that has a REQUIRE-MATCH argument 
is completing-read (l.1722).

Since in read-buffer the function completing-read is called with the 
argument require-match (l.1237), I think the doc string should read like 
this:

"Optional third arg REQUIRE-MATCH determines whether non-existing
  buffer names are allowed.  It has the same meaning as the
  REQUIRE-MATCH argument of the `completing-read' function."

This patch will fix it accordingly:

+ REQUIRE-MATCH argument of the `completing-read' function.
  The argument PROMPT should be a string ending with a colon and a space.
  If `read-buffer-completion-ignore-case' is non-nil, completion ignores
  case while reading the buffer name.
