Trim whitespace during head and tail string elision.

All string elision that removes the head or tail of a string will now
remove any whitespace adjacent to the elision point as well.

Furthermore, eliding the beginning of a string will never result in more
unicode codepoints or bytes than was initially requested. Previously,
it was possible to end up including a character with combining marks or
a character whose codepoint was split by the target number of
characters.

This does affect filename elision. For example, eliding "foo bar.gif" to
the width of 9 characters results in "foo….gif" rather than "foo ….gif",
because the filename elision logic elides the tail of the base filename
rather than eliding the middle of the full filename.
