I found a macro use bug in file src/pr.c of textutils-1.4.  The file
src/pr.c has a line:

              if (!ISDIGIT (*++s))

in function main, while another file src/system.h defines the macro
`ISDIGIT' as follows.

#define ISDIGIT(c) (isascii (c) && isdigit (c))

So the pointer `s' is incremented twice if macro `isascii' is defined
by the system.
