configure broken if layout begins on first line of config.layout

           Summary: configure broken if layout begins on first line of
                    config.layout
           Product: Apache httpd-2.0
           Version: 2.0.43
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: Minor
          Priority: Other
         Component: Build
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: sk@sethwklein.net

The configure script is broken if the selected layout begins on the first line of config.layout.

To reproduce:

cd httpd-2.0.43
mv config.layout config.layout.orig
sed -n '13,34p' config.layout.orig | tee config.layout ./configure
# the result is an exceedingly unobvious error from the APR sub configure
# script which complains about "--bindir: NONE/bin"
sed -n '12,34p' config.layout.orig | tee config.layout ./configure
# works

This is with GNU Sed 4.0.4 which is relevent because the problem is with the sed program that configure uses to parse config.layout.

The following patch (which i will also attach, if the system lets me) fixes the problem for me.

I am tempted to indulge in a rant about the wisdom of using configure args instead of weird config files in this situation but this bug report is hardly the place.
