POSIX requires the shell to sanitize PWD at startup rather than relying
on the (possibly-incorrect) value that it may have inherited from the
environment. But knowing whether a shell follows the POSIX rules on PWD
could indeed be useful for deciding portable workarounds and/or altering
the shell probing done at the front of autoconf scripts to pick a better
shell.
