Stream opened with popen() should be closed with pclose() as documented
in popen(3) man.
At least on FreeBSD SDCV_PAGER wasn't usable, because fclose() doesn't wait for child process (pager) and after termination of sdcv less/more also is terminated. Difference probably not between Linux/BSD, but between different implementations of fclose() in glibc and BSD libc or in llvm libc++ and GNU Standard C++ Library. Anyway pclose() should be used here.
