#312 tests/general: ilib, utf8, utf8_ovld append random trailing spaces

[Charles Evans]

in tests/general:
utf8.icn
utf8_ovld.icn
ilib.icn
have random trailing spaces.
tests/Makefile.test uses
diff -w
to test them, and therefore has been ignoring the errors.
git checkout 9/24 be2017
ubuntu focal
gcc 9.3
default config, all + but no VOIP
./configure --enable-ovld
only for utf8_ovld

[Charles Evans]

diff -w is bug [#311]

[Charles Evans]

iconc -fl -fd ilib
same as unicon ilib
for both only whitespace at EOL differs from ilib.std
