Hello!
When using meta-commands in the repl (without readline support), if
reading an expression parameter fails, the rest of the input gets read
in anyway. An example interaction:
--8<---------------cut here---------------start------------->8---

scheme@(guile-user)> ,trace "\m"
Throw to key `read-error' while reading argument `form' of command
`trace':
In procedure scm_lreadr: #<unknown port>:1:11: illegal character in
escape sequence: #\m
"
$1 = "\n"
scheme@(guile-user)> ,trace "\m123
Throw to key `read-error' while reading argument `form' of command
`trace':
In procedure scm_lreadr: #<unknown port>:2:11: illegal character in
escape sequence: #\m
$2 = 123
--8<---------------cut here---------------end--------------->8---
Since Geiser uses meta-commands with multi-line expressions to
communicate with Guile it can get very confusing if you have syntax
errors in your code.
