I suspect the problem is here in src/helper/startup.tcl
set errmsg [format "%s: command requires more arguments" \
[concat $name " " $args]]
The backslash newline sequence will likely have a carriage return inserted.
The easy solution is to ensure that these startup files are read in text mode
or have the \r\n translated to \n before creating startup_tcl.c
But it would also be nice if each startup script were evaluated independently
with the original filename, and any error message shown.
