Modified Files:
        src/bin/sh: input.c

Log Message:
Mostly DEBUG and white space changes.   Convert DEEBUG TRACE() calls to
the new format.   Also #if 0 a function definition that is used nowhere.
While here, change the function of pushfile() slightly - it now sets
the buf pointer in the top (new) input descriptor to NULL, instead of
simply leaving it - code that needs a buffer always (before and after)
must malloc() one and assign it after the call.  But code which does not
(which will be reading from a string or similar) now does not have to
explicitly set it to NULL (cleaner interface.)   NFC intended (or observed.)
