posixoptions.7: Fix legacy functions list (s/getcwd/getwd/)
Alan:
[
The on-line copy of the manual page "posixoptions(7)" dated
2018-04-30 has an entry for "getcwd()" in the section headed
"XSI - _XOPEN_LEGACY - _SC_XOPEN_LEGACY".
I believe that entry should be "getwd()" as that is the API call
which was present in X/Open-6 but withdrawn in X/Open-7.
]
mtk: confirmed by reviewing the table ("Removed Functions and
Symbols in Issue 7") at the end of Section B.1.1 on page
3564 of IEEE Std 1003.1, 2016 Edition.
