The input backslash-null is metafiled by shingetline() to
backslash-meta-space (since 0 xor 32 = 32 = ' '), but it seems
the lexer does not treat the meta after backslash specially and
interprets the space as a word separator; this results in a
word ending with meta.
What is the "correct" behavior for the input backslash-null?
The following may be a possibility but I'm not sure.
(The ifdef DEBUG part is copied from line 1059 in the same file)
diff --git a/Src/lex.c b/Src/lex.c
