This may be enough to support the various existing formats that are offered by "git branch" and/or "git tag", but I do not think if this is the right approach in the longer term, or if we are painting ourselves in a corner we cannot cleanly get out of later [*1*]. Will the "refname" stay to be the only thing that may want alignment padding appended in the future? Will it stay true that we want to align only to the left? Etc., etc. Cc'ed Duy as %< in the pretty-format was his invention at around a5752342 (pretty: support padding placeholders, %< %> and %><, 2013-04-19). > diff --git a/ref-filter.c b/ref-filter.c > index dd0709d..3098497 100644 > --- a/ref-filter.c > +++ b/ref-filter.c > @@ -10,6 +10,7 @@ > #include "quote.h" > #include "ref-filter.h" > #include "revision.h" > +#include "utf8.h" > > typedef enum { FIELD_STR, FIELD_ULONG, FIELD_TIME } cmp_type; > > @@ -695,7 +696,23 @@ static void populate_value(struct ref_array_item *ref) > int num_ours, num_theirs; > > formatp++; > - if (!strcmp(formatp, "short")) > + if (starts_with(formatp, "shortalign=")) { When adding a new thing to an existing list, we prefer to append it at the end of the list, if there is no other reason not to do so (e.g. "the existing list is sorted in this order, and the new location was chosen to fit the new item to honor the existing ordering rule" is a valid reason to put it at the beginning, if the existing sorting rule dictates that the new thing must come at the beginning). > + const char *valp, *short_refname = NULL; > + int val, len; > + > + skip_prefix(formatp, "shortalign=", &valp); > + val = atoi(valp); In newer code, we would want to avoid atoi() so that "foo:shortalign=1z" that is a typo of "12" can be caught as an error.

If a user wants to align the refs that are usually usually short start the next thing at the 8th column, which should she use?
