The git log --graph --show-signature command incorrectly indents the gpg
information about signed commits and merged signed tags. It does not
follow the level of indentation of the current commit.

Example of garbled output:
$ git log --show-signature --graph

In log-tree.c modify show_sig_lines() function to call graph_show_oneline()
after each line of gpg information it has printed in order to preserve
the level of indentation for the next output line.
