    strbuf: introduce strbuf_getline_{lf,nul}() · 8f309aeb
    Junio C Hamano authored
    The strbuf_getline() interface allows a byte other than LF or NUL as
    the line terminator, but this is only because I wrote these
    codepaths anticipating that there might be a value other than NUL
    and LF that could be useful when I introduced line_termination long
    time ago.  No useful caller that uses other value has emerged.
    
    By now, it is clear that the interface is overly broad without a
    good reason.  Many codepaths have hardcoded preference to read
    either LF terminated or NUL terminated records from their input, and
    then call strbuf_getline() with LF or NUL as the third parameter.
    
    This step introduces two thin wrappers around strbuf_getline(),
    namely, strbuf_getline_lf() and strbuf_getline_nul(), and
    mechanically rewrites these call sites to call either one of
    them.  The changes contained in this patch are:
    
     * introduction of these two functions in strbuf.[ch]
    
     * mechanical conversion of all callers to strbuf_getline() with
       either '\n' or '\0' as the third parameter to instead call the
       respective thin wrapper.
    
    After this step, output from "git grep 'strbuf_getline('" would
    become a lot smaller.  An interim goal of this series is to make
    this an empty set, so that we can have strbuf_getline_crlf() take
    over the shorter name strbuf_getline().
