It's possible that this is something that fundamentally cannot be
fixed, but maybe not. Would someone please take a look, DTRT, and
then ack?

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:
* emacs -Q
* M-x shell RET
(assuming sh-type command interpreter)
* in *shell* buffer:
$ PS1='x -y $ '
x -y $ ls -l >/dev/null
x -y $
Once the ls command is entered on the second line, the -y in the
prompt gets highlighted the same way that the -l in the ls command
gets highlighted.
doing `C-u C-x =' on the `y' in the prompt on the last line gives:
character: y (121, #o171, #x79, U+0079)
charset: ascii (ASCII (ISO646 IRV))
code point: #x79
syntax: w which means: word
category: a:ASCII l:Latin
buffer code: #x79
file code: #x79 (encoded by coding system iso-latin-1-unix)
display: by this font (glyph code)
-outline-Bitstream Vera Sans Mono-normal-i-normal-normal-11-82-96-96-c-*-
iso8859-1 (#x79)
There is an overlay here:

font-lock-face comint-highlight-prompt
There are text properties here:
face font-lock-comment-face
field output
fontified t
inhibit-line-move-field-capture t
rear-nonsticky t
Doing the same on the second, now fontified, prompt gives:
character: y (121, #o171, #x79, U+0079)
charset: ascii (ASCII (ISO646 IRV))
code point: #x79
syntax: w which means: word
category: a:ASCII l:Latin

font-lock-face comint-highlight-prompt

I've seen this in other comint-like buffers as well (*sql*). Is there
a way to protect/prevent the prompt string from being font-lock'd?

The following patch seems to fix the problem by adding the face property to
the overlay as well.

That's not correct though -- using `font-lock-face' instead of `face'
was intentional, to allow highlighting to be toggled using M-x font-lock.
I suppose the right solution is to make the font-lock expressions used
by comint avoid any region that's inside a prompt, but I don't know how
to do that.

There reason for the font-lock-face property is so that it won't
actually appear on the display unless Font-Lock mode is enabled.
In effect, it is a way to "manually" implement fotification
in a certain major mode. Your change would override this
and display the face even if Font-Lock mode is disabled.
That's not correct.
Since comint uses font-lock-face instead of specifying fontification
rules, it surprises me that the `face' property is placed on anything.
Maybe that comes from Shell mode, from shell-font-lock-keywords.
That seems like an inconsistency, somewhat. Maybe that is the cause
of the problem.
If you can put the `face' property on the overlay
only when the text it is over has a `face' property,
then I think it will be correct, because when Font-Lock is off
it won't do anything. Could you do it that way?

[Sorry for the delay -- I've been offline for a bit]
I tried this and it's no-go. The face due to font-lock isn't getting applied until after the
prompt is processed in the output filter. I'm far beyond my expertise here so I'll drop this.

I don't understand the description of the problem -- could you spell
it out more?

Why not do the opposite: check the presence of a font-lock-face char
property before returning a non-nil face in font-lock-keywords.
