I solved that problem with regular expressions resp. substitutions, see
currently after line 1112 in function gibbon_position_format_move().

My approach depends on the point pairs involved in a move on being
sorted, so that movements with the rearmost checkers appear first.

Then I convert the integer pairs into a string, for example something
like "a/c c/e f/h h/j" (for "24/22 22/20 19/17 17/15").  The rest is
done by the glib regex engine, for example

    s/\/([a-z]) \1\//\//g

compresses the above string into "a/e f/j".  Inserting the '*' for blot
hits or grouping identical movements with "(2)", "(3)", or "(4)" works
essentially the same, only it's more complicated.

Maybe buggy, maybe inefficient, but I still like my function. ;)
