+7. POSIX compliance                                    *posix-compliance*
+
+In 2005 the POSIX test suite was run to check the compatiblity of Vim.  Most
+of the test was executed properly.  Here are the few things where Vim differs:
+
+The -w{number} and -w {number} command line arguments are not supported by
+Vim.
+                                                       *posix-screen-size*
+The $COLUMNS and $LINES environment variables are ignored by Vim if the size
+can be obtained from the terminal in a more reliable way.  Set the $VIM_POSIX
+environment variable to have $COLUMNS and $LINES overrule sizes obtained in
+another way.
