[bugs #12064] make distclean deletes a distributed file

[anonymous]

Follow-up Comment #4, bugs #12064 (project findutils):

I did some follow-up work on this.

The problem is that bash prints the current directory
after a `cd' if CDPATH is defined.

So this code in import-gnulib.sh:

printf "%s" "EXTRA_DIST = "
cd  gnulib/m4
ls *.m4 | sed -e 's/$/ \\/' | sed -e '$ s/\\$//'

had undesired extra output from the cd command.

Note that automake, for example, is also careful to
unset CDPATH.

./share/autoconf/m4sugar/m4sh.m4:220:# CDPATH.
./share/autoconf/m4sugar/m4sh.m4:221:$as_unset CDPATH

If you don't have enough to worry about, you might
also want to worry about IFS...
