[gcc patch 3/3] cp-demangle.c: Fix DMGL_RET_POSTFIX for inner func types

[Jan Kratochvil <jan.kratochvil@redhat.com>]

Hi,

I do not need this patch in any way but I believe it should go in for the case
anyone would want to use DMGL_RET_POSTFIX with C/C++.

Without this fix the new testcase would:
FAIL at line 3979, options --format=gnu-v3 --ret-postfix:
in:  _Z6outer2IsEPFilES1_
out: outer2<short>(int (*)(long))int (*(int (*)(long)))(long)
exp: outer2<short>(int (*)(long))int (*)(long)


Thanks,
Jan
