New submission from Дилян Палаузов:
Providing that during ./configure Py_DEBUG can either be set or not, but there
is no third state, which third state would justify calling ./configure
--with-pydebug=lambda, --with-pydebug shall be renamed to --enable-pydebug .
Likewise for --with-pymalloc , but it is more tricky. Currently ./configure
--help emits "--with(out)-pymalloc disable/enable specialized mallocs".
Usually from the output of ./configure --help one shall be able to conclude,
whether a switch is on or off by default, if it is not provided. E.g. if it is
by default off, then "--enable-X enable feature X" is printed; and
"--disable-Y disable feature-Y" is printed when by default the feature is on.
The code says, that if pymalloc is enabled implicitly, if neither
--with-pymalloc nor --without-pymalloc is provided. Let's update the
AS_HELP_STRING to show the default and also shorten the code, which makes it
also easier to understand (for me at least)
