I'm happy to leave the shell magic -- and even the semantics -- to you. :-)

I just don't want to have to type ${PWDCMD-pwd} all over the place in
Makefiles; it's too error prone and it's two hard to read.  This is like
writing:

  (pwdcmd ? pwdcmd : "pwd")

all over the place in a C program; we should factor it out into a single
place.
