Hi,

I've noticed that in contexts where escape sequences are expanded
and \c's should not be recognized (i.e., not in arguments to the
various printing commands), then a \c is actually treated synonymous
to \U.  The attached patch contains a fix.

While inspecting the code I came across another glitch:  If a \c
occurs in the separator string of a $arr[(pws:...:)...] subscript,
it is not treated like an unrecognized sequence (i.e., replaced by
a "c"), but removed completely.  (Note that ${(p...)...} gets this
right.)  The attached patch also fixes that.

Finally, I've discovered that \c in an argument to a printing command
only suppresses the final newline, but according POSIX it should
suppress all output after the \c, and that's what ksh, bash, and
echo/printf from GNU coreutils do.  So is the current behaviour really
desired, or should I send a patch to change it?

Best regards
