In read_rebase_todolist() every line is, after reading, checked
for a comment_line_char. After that it is trimmed via strbuf_trim().
Assuming we do never expect a CR as comment_line_char,
strbuf_getline_lf() can be safely replaced by its CRLF counterpart.

Notes:
Looking at the code in read_rebase_todolist(), the
lines are read, checked for a comment_line_char and then trimmed. I
wonder why the input is not trimmed before checking for this character?
Is it safe to replace strbuf_getline_lf() by strbuf_getline() anyway?
The only case I can imagine that could lead to unexpected behaviour then
would be when someone sets the comment_line_char to CR. How likely is that?
Why is the trim _after_ checking for the comment char anyway? Should
something like " # foobar" not be considered as comment?
I decided to roll out the patch because I considered it not as a risk to be
taken seriously, that the comment line char will be '\r'.
Meta-question: Should something of this discussion be put into the commit?
