Move to start/end of word keybindings (b and w) halt at accented characters

[BeanieBarrow]

If a word contains an accented character, then pressing b or w in normal mode only jumps to the character before/after said letter instead of the first or last character of the word.

See this in action on an iconic Hungarian phrase that is used to test programs' and fonts' behavior with accented characters:

iamb_accented_characters_bug.mp4

A rephrasing of this issue could be that these kinds of special characters get treated as whitespace or punctuation.

Thank you for reporting this! I've fixed it at ulyssa/modalkit#109 and added the example to the tests. I'm going to cut a modalkit release that includes it, and I'll bump the dependency in iamb.

I updated to [email protected] as part of #45 , so I'll mark this as done.
