7561	Make ChimeraX fetch 8 character PDB identifiers	Tom Goddard	Eric Pettersen	"The PDB announced they will start using 8 character PDB identifiers.  These identifiers are already in all PDB mmcif files from August 2021 on.  Once they run out of 4 character identifiers, any new entries will only be available using 8 character identifiers.  And they say those will only be provided in mmCIF format.

Our current fetch command ""open 1a0m"" looks specifically for 4 character identifiers and will need to handle 8-character identifier too.  Probably should also check that it is alpha-numeric with no ""."" to avoid mistaking 8 character filenames for identifiers.  Also the code may need a change to the fetch url since the PDB also seems to be putting a ""pdb_"" in front of the 8 character identifier in most places."	enhancement	closed	moderate		Input/Output		fixed		Greg Couch				all	ChimeraX
