[PATCH v3 3/3] ref-filter: use pretty.c logic for trailers
From: Hariom Verma <hariom18599@gmail.com>
Now, ref-filter is using pretty.c logic for setting trailer options.
New to ref-filter:
:key=<K> - only show trailers with specified key.
:valueonly[=val] - only show the value part.
:separator=<SEP> - inserted between trailer lines.
:key_value_separator=<SEP> - inserted between key and value in trailer lines
Enhancement to existing options(now can take value and its optional):
:only[=val]
:unfold[=val]
'val' can be: true, on, yes or false, off, no.
