What I was thinking of was getting rid of the whole "align" feature where
you provide a value to which it would align.
Something like: --format="%(item:modifieralign)" which would use something
on the lines of what the max-width calculator in branch -l uses, to get the max
alignment size. But the problem is that ref-filter goes through the refs using
a function which has no connections with the atoms used. So a more practical
solution would be --format="%(item:modifieralign=X)" where we could provide a
means of calculating X via ref-filter. Something like this in tag.c:
int max_width = get_max_width("<item to get max_width of>");
use this max_width to then do a
--format="%(item:modifieralign=X)", where X = max_width
What do you think?
