After running that I get this in the abc buffer for
M-x describe-variable RET comint-prompt-regexp RET
,----
| comint-prompt-regexp is a variable defined in ‘comint.el’.
| Its value is "^[^#$%>
| ]*[#$%>] *"
| Local in buffer abc; global value is "^"
|
| Documentation:
| Regexp to recognize prompts in the inferior process.
| Defaults to "^", the null string at BOL.
|
| This variable is only used if the variable
| ‘comint-use-prompt-regexp’ is non-nil.
|
| Good choices:
| Canonical Lisp: "^[^> \n]*>+:? *" (Lucid, franz, kcl, T, cscheme, oaklisp)
| Lucid Common Lisp: "^\\(>\\|\\(->\\)+\\) *"
| franz: "^\\(->\\|<[0-9]*>:\\) *"
| kcl: "^>+ *"
| shell: "^[^#$%>\n]*[#$%>] *"
| T: "^>+ *"
|
| This is a good thing to set in mode hooks.

`----
The first hash is not recognized as a prompt, but the rest are.
If you really need to use the hash, then running
: (set-local comint-prompt-regexp "^[^$%>\n]*[$%>] *")
in the `abc' buffer might help.
This has obvious problems if you run as root and do not reset the prompt to
something other than #.
HTH,
