autoconf 2.53: trivial whitespace fix.

[Keith Bostic]

The AH_CHECK_HEADERS_DIRENT macro:

    # AH_CHECK_HEADERS_DIRENT(HEADERS...)
    # -----------------------------------
    m4_define([AH_CHECK_HEADERS_DIRENT],
    [AC_FOREACH([AC_Header], [$1],
      [AH_TEMPLATE(AS_TR_CPP(HAVE_[]AC_Header),
                   [Define to 1 if you have the <]AC_Header[> header file, and
                    it defines `DIR'.])])])

splits its comment over two lines:

    /* Define to 1 if you have the <dirent.h> header file, and it defines `DIR'.
       */
    #define HAVE_DIRENT_H 1

unlike the rest of the comments, which confused a tool we have
that post-processes the config.h file.  I realize that we should
not have depended on this behavior, but it seems reasonable to
be consistent, where possible.
