 Fix identifier parsing in hp2ps

 Now identifiers can start with a package key, which is a hash, so they
 may also start with a digit. Identifiers always appear at the beginning
 of a line, and numbers never appear here, soit's safe to allow
 identifiers to start with a digit.

 Test Plan: `concprog002` passes under `threaded2_hT` way
