Re: [PATCH] utf8: add utf8_strwidth()

I know next to nothing about our encoding functions, but this seems
suspiciously similar to utf8_width in utf8.c. There is also a
git_wcwidth, but I don't know how they relate.

git_wcwidth determines the screen columns of a single ucs_char_t. 
utf8_width returns the git_wcwidth of the first character in a string. 
utf8_strwidth (the function added by this patch) is a simple loop around 
utf8_width, because writing the loop every time would be silly.

On that note, there are probably more cases in the code that ought to use 
something like utf8_strwidth. I only noticed this one case because I'm 
working on a project with someone with an accented letter in his last 
name.
