20832	NeedlemanWunch.matches_to_gapped_seqs() modifies arguments	Tom Goddard	Eric Pettersen	I tried using NeedlemanWunch.matches_to_gapped_seqs(match_list, ...) to convert a match list to a pair of gapped sequences.  Then I spent the next hour debugging because it reverses the match_list input argument.  So the next time I call it with the same match_list list object all hell breaks lose giving an absurd pair of gapped sequences.  The code should probably not modify its input arguments.	defect	assigned	moderate		Sequence								all	ChimeraX
