Problem Description:
I am running Cygwin B20.1 (1/15/99 cygwin DLL snapshot) bash under Win 95, and have problems
"catting" files to the screen (which is a DOS box). For example, a 9-line file will cat correctly 3
times in a row, then on the 4th try leave out some characters, then on the 5th try get it right
again. The problem is exacerbated when I run Charles Wilson's "consize" utility to increase the
line history buffer, but appears without it; see below. The source file, an example session, and
the output of cygcheck are edited in following. Can you give me any hints on what's wrong, and how
to fix it?

===============================================================
Copy of 9-line file used to exhibit screen-display problem follows. File begins with
"/* printIt"... and ends with ..."buffer[256]".
/* printIt: This program lists a file to the screen, adding line numbers. */
/* Usage: printIt filename */
#include <stdlib.h>
#include <stdio.h>
void do_heading(char *filename);
int line, page;
char buffer[256];
==========================================================================================
Text of CygWin bash session illustrating (one aspect of) screen display problem follows.
In summary, 9-line text file shown above is successfully catted to screen 3 times in a row,
then the cat has an error on the fourth try, and it returns to nominal on the fifth and
last. Lines that are indented and parenthesized are comments interpolated later to highlight
what the problem is. Note that original file as pasted in above contains a tab character
at beginning of last line, just prior to phrase "char buffer[256]". For some reason, this
character is reproduced below as a sequence of spaces.
BASH.EXE-2.02$ cd /E/Compiler/CygWin/GSSCodes
(Change to directory with example file.)
BASH.EXE-2.02$ cat frontOfPrintIt.txt

including the comma in line 8 through the tab in line 9 has gone to bit heaven.)
