bug#399: 23.0.60; comint-dynamic-complete doesn't complete name of executable in current directory

[Eric Hanchrow]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I started emacs  -Q -nw
I typed M-x shell RET
In the shell, I typed cd ~/kits/CoziExampleTest/ RET
  (that directory contains an executable file named test.py)
In the shell I typed ./te TAB
I expected to see emacs insert the rest of the file name, so that the final 
line read ./test.py.
Instead, nothing happened.
Note, however, that when I typed "ls ./te TAB", completion _did_ work: I saw 
"ls ./test.py"

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/src/emacs-with-my-tweaks.git/etc/DEBUG for instructions.
