[GiNaC-devel] Another bug fix for the polylogs

[Stefan Weinzierl]

Hello,

attached is patch for a bug fix in the file inifcns_nstdsums.cpp.
This bug is not related to any bug reported in January.
The bug manifest itself that G-functions with trailing zeros and y<>1 are 
not calculated correctly.

Description:

The method G_do_hoelder is called from the method G_numeric.
G_do_hoelder expects arguments without trailing zeros.
(The reason is that G_do_hoelder uses the scaling relation, which is only 
valid for G-functions without trailing zeros.)
Trailing zeros are handled by the method G_do_trafo.
The patch ensures that the method G_numeric calls in the case of trailing 
zeros the method G_do_trafo and not G_hoelder.

  Best wishes,

    Stefan
