Subject: strbuf: add new function strbuf_getwholeline()
X-Git-Tag: v1.6.5-rc0~54^2~3
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c7e4f0d78aaac33d5e3cec54cddd40439e77d16c;p=git.git

strbuf: add new function strbuf_getwholeline()

This function is just like strbuf_getline() except it retains the
line-termination character.  This function will be used by the mailinfo
and mailsplit builtins which require the entire line for parsing.
