Not a general solution, but for PDB chains you could use an extra
underscore for the lower case ones.
For EMBOSS .... well, we could play with the way databases work. Not all
access methods allow case sensitive searching, but we could fetch all
entries and try to reject those that do not match. This would need
something in the EMBOSS id. We already allow modifiers after the id to
set sequence ranges pdbprot:1fbt_a[1:20] or we could add a qualifier
-scasesensitive for all sequence inputs.
