* src/cff/cffdrivr/c (cff_get_ps_name): Avoid unnecessary crash. The situation can happen if `FT_New_Face` (or one of its siblings) is called with a negative index to get the number of contained faces, followed immediately by a call to `FT_Get_Postscript_Name`. While this is not a valid use of the FreeType library there is no need for a crash. Fixes #1219.
