Problem with compilation of (La)TeX files in emacs 22

I'm trying to compile (La)TeX files from within Emacs, by using
tex-file.  The shell I'm using is bash 3.2.5 (Cygwin), and the only
variable I have changed from the default is tex-command (which contains

If there is no *tex-shell* buffer open, the compilation via C-c C-f
works fine for the first time.  However, subsequent C-c C-f's will not
cause pdflatex to be invoked.  The only thing that happens is that the
shell prompt gets duplicated in the last line of *tex-shell*.  Please
refer to the following output:

 [20:11 address@hidden foo] pdflatex \\nonstopmode\\input foo.tex
 This is pdfeTeX, Version 3.141592-1.30.6-2.2 (MiKTeX 2.5)

     [... pdflatex output omitted ...]

 Output written on foo.pdf (2 pages, 79161 bytes).
 Transcript written on foo.log.
 [20:11 address@hidden foo] pdflatex \\nonstopmode\\input foo.tex

 [20:11 address@hidden foo] [20:11 address@hidden foo]

Digging a little deeper into this problem, it seems to be caused by
tex-send-command in tex-mode.el.  Somehow, comint-send-input appends two
line feeds at the end of the command that is sent to *tex-shell* (I can
see that in the hex dump of the shell buffer content).

Changing (comint-send-input) to (comint-send-input t) in
tex-send-command seems to fix the problem for me.  Not sure if that's a
correct fix, or just avoiding the symptom...
