I still can't reproduce this problem. Does anyone on emacs-devel see
the bug?

AFAIU that has nothing to do with emacs, but with
file-permissions: `foo' isn't executable, "x" it wasn't set.

Text properties break shell mode by making motion commands erratic
and unpredictable, so all comint modes are now worse than useless.
BOLD rendered as upper case for illustration ...
$ LS BAr FOO
foo
$ FOO
bash: ./foo: Permission denied
$ HISTORY
... ls foo
... foo
... history
$
... your command got left-truncated, a variation on the usual lossage
where return sends only command characters up to the next font change,
then sends a newline, the remaining characters up to end of line are
not sent, a potentially catastrophic failure.

I have seen this intermittently for a long time now, but still haven't
been able to reproduce it reliably.
