[Bioperl-l] Parsing FASTA m10 output

[aaron.j.mackey at gsk.com]

Since -m10 is newer than PGM_DOC, you should be fine to use the first line 
as a detection for m10, when that first line exists (when it does not, the 
format cannot be m10, unless someone has re-compiled FASTA with an 
undefined PGM_DOC).
