It also fixed the scan bug that I had earlier reported. It did so, at least in
my environment, by displaying a question mark in place of the strange Unicode
character. nmh 1.6 displayed the actual character, though it messed up the
spacing. Either approach is fine with me. I prefer the 1.7 approach, though
others may differ.
Well, we were trying to get smarter about these things. It messed
up the spacing in 1.6 because wcwidth() returned -1 (which means
"not printable") so that confused the spacing calculator. That was
"improved" by adding an assertion for 1.7, but we didn't realize that
characters that passed other tests might not be printable, so that's
why you had that assertion. Now we correctly handle this case and if
wcwidth() returns -1 we decide it's unprintable and return the substitution
character.
