When pager setup succeeds, the second run is a noop, because isatty(1)

fails, so we do try again. And I can reproduce your problem with:

No, it's not a noop such as that it's clear that things are different on
the second call.

Here I meant that setup_pager() is effectivelly called from 2 different places:

First backtrace:
setup_pager()
commit_pager_choice()
run_builtin()
handle_builtin()
run_argv()
cmd_main()

Second backtrace:
setup_pager()
cmd_log_init_finish()
cmd_log_init()
cmd_show()
run_builtin()
handle_builtin()
run_argv()
cmd_main()

Also, isatty(1) is not false in neither of the calls. Otherwise I
wouldn't hit this bug (pager would be NULL and setup_pager() a noop as
you said).


Cheers,

Enzo
