Re: [PATCH v2 16/17] grep: read -f file with strbuf_getline_crlf()

Hi Junio,

This is iffy; you may actually be trying to find a line with ^M in
it on a system whose line ending is LF.  You can of course work it
around by having a line that has "^M^M^J", let the strbuf_getline_crlf() eat
the last "^M^J", leaving just the single "^M" as the pattern.

Thanks for being careful.

Having said that, `grep` operates on lines of text, and CR is established
as a non-text byte, so I would argue that the previous behavior was
actually incorrect: if you searched for, say, `abc$` in a CR/LF delimited
file, the outcome would not have met my expectation of correct behavior.

Ciao,
