#71036: watch: --enable-watch8bit may be needed, else it may mangle UTF-8 output by
commands

 By default the **watch** command seems to mangle UTF8 output:

 {{{
 $ watch echo "MacPortsさん、こんにちは！"
 }}}

 results in:

 {{{
 Every 2.0s: echo MacPortsさん、こんにちは！

 MacPorts      M-M-M-M
 }}}

 Note that the banner looks OK, but the actual output of the command gets
 mangled into those "M-M-" stuff.

 The configure script has an option to fix that: `--enable-watch8bit`, I
 also needed to apply an additional fix in watch.c itself and remove the
 "ncursesw/" prefix from the ncurses include. Afterwards the output looks
 as we would expect:

 {{{
 Every 2.0s: echo MacPortsさん、こんにちは！

 MacPortsさん、こんにちは！
 }}}
