Hmm, we would punish those with ridiculously long remote name by
truncating at n but that is OK.
We use buffer[BUFSIZ] to read various things in this file, not just
$GIT_DIR/branches/* files, with fgets(), which may be better done if
we switched to strbuf_getline(). Then we can also use trim family
of calls from the strbuf API suite.
Move to strbuf_getline() may be a doubly attractive proposition,
with a possible change to strbuf_getline() to make it also remove CR
that immediately precedes LF [*1*], helping DOSsy platforms.
