Does getopts actually need to depend on unicode-width? #132
Description
Currently the unicode-width crate is used to determine where to wrap help text. The standard library libtest crate doesn't use this functionality and is unlikely to ever do I think given the code size overhead that adding translation support to libtest would imply for all test executables. And rustc and rustdoc don't currently use this functionality either. At the same time the unicode-width crate takes up 1.5MB of source code given the huge table with widths of each character. This is a non-trivial part of the size vendored standard library sources would take.
Another option would be to vendor the getopts crate into the rust repo and strip it down as necessary. Using the same crate inside both the library and compiler workspace is non-trivial however.
