so... i wonder if fg (after this last fix) used the ascii sort order, and if not, which?

it sorted my list, but this time, it put [space] after [hyphen] -- as a matter of fact, it put [space] as last sort order -- as in:

136-p2x concluding p2
136-p3-1 title
136-p3-3m07
136-p3-4o3
136-p3x concluding p3
136-p3 *** part 3 <-----

so now i have to reassign / re-title a bunch of entries, then add [hyphen] to sort properly:

136-p2x concluding p2
136-p3-0 *** part 3 <-----
136-p3-1 title
136-p3-3m07
136-p3-4o3
136-p3x concluding p3

i think the fix used a different convention where [space] is not first in sorting.

anyway, a bit of a mess, throwing a bunch of things out of order so i had to rename stuff. ugh lol
