Steps to reproduce


$ git clone https://git.maneage.org/project.git
$ cd project
$ ./project configure
...
Please enter the top build directory: ../project-build/


Expected result:
The directory is accepted, as it is not under the source-directory.

Current result:

 ** The build-directory cannot be under the source-directory.


The problem lies in comparison done in lines
939-940:reproduce/software/shell/configure.sh


 936         # If it is given, make sure it isn't a subdirectory of the
source
 937         # directory.
 938         if ! [ x"$bdir" = x ]; then
 939             if echo "$bdir/" \
 940                     | grep '^'"$currentdir" 2> /dev/null > /dev/null;
then


Using «grep '^'"$currentdir/"» fixes the problem (at least here).
