install-sh

btw, fwiw, i was having trouble running ./configure (both in 1.4.5 and
git), as i would get an error message:
----
configure: error: cannot find install-sh or install.sh in . ./.. ./../..
----

i googled, got

http://stackoverflow.com/questions/11226523/autoconf-not-generating-makefile
----

which says, in *that* (non-ratpoison) case, the problem was a missing
"AM_INIT_AUTOMAKE([1.9 foreign])", and that a workaround was to
----
autoreconf -f -i -Wall,no-obsolete
----
which i did (in git), and ./configure (and the subsequent make) then ran
successfully.  (i never have understood autoconf, et al., so i'm just
following blindly.)

cheers, Greg
