Form its inception (back in May of 2011), escaped_copy
has always been a flawed function. It does not operate
on 'escaped' strings but instead treats all input as a
regular string incapable of containing utf8 sequences.
As such, it should only be used for strings guaranteed
to NOT contain multibyte characters (like supgid). For
all other strings, which could contain utf8 stuff, the
correct function should have been that escape_str guy.
So this commit changes nearly every escaped_copy call.
[ note: unlike the newlib guy, the master ps program ]
[ cannot properly handle utf8 multibyte sequences in ]
[ in the recently introduced 'exe' field shown below ]
