PatR d69f0787be add '(uchar)' casts to ctype calls
This is from the pull request for the assertion failure fix.  It
did not mention how to reproduce the assertion failure, just added
casts to a bunch of isspace/isprint/tolower calls that didn't already
have such.

I removed an obsolete change for win/tty/topl.c and changed the
win/win32/mswproc.c code to avoid using an expression with side-effects
(*colorstring++) in calls to tolower() in case someone overrides that
with a macro which evaluates its argument more than once as some pre-
ANSI ones used to do.  Not tested, might have typos....

sys/wince/*.c still needs similar casts.
