If it is known to have 40-hex:
(1) accepting ">= 0" seems way too lenient. You only expect a
41-byte file (or 42 if somebody would write CRLF, but I do not
think anybody other than yourself is expected to write into
this file, and you do not write CRLF yourself);
(2) strbuf_trim() is overly loose. You only want to trim the
terimnating LF and it is an error to have other trailing
whitespaces.
I think the latter is not a new problem and it is OK to leave it
as-is; limiting (1) to >= 40 may still be a good change, though,
because it makes the intention of the code clearer.
