[PATCH] parse_omit_name should increase num of fields before appending encoding

[Hong Xu]

parse_omit_name currently does not increase number of fields to 12 after
appending encoding, This does not lead to the correct font is a xlfd
like "-*-*-medium-r-*-*-33-*" is given.

Please note that the "if" in this patch is replaced by "while". The
reason is that I found the commit 3d69b0a83e62f8f6fbd changed the
"while" to "if", which does not seems logically correct for me and
actually accidently "fixed" the bug
