Subject: vis-menu: improve empty prompt handling (vis-menu -p '')

The textw{,n} functions should probably be changed to not
accomodate for leading and trailing spaces. They should also
be changed to properly calculate the display width of an UTF-8
encoded string. Currently they will just return the number of
codepoints which is obviously wrong.
